Simultaneous equations can be solved by substitution, elimination, graphs and by matrices.

The values of x, y and z are:

The equations are given as:

[tex]\mathbf{-x - y -z = -8}[/tex]

[tex]\mathbf{-4x + 4y +5z = 7}[/tex]

[tex]\mathbf{2x +2z = 4}[/tex]

Make z the subject in [tex]\mathbf{2x +2z = 4}[/tex]

[tex]\mathbf{2z = 4 - 2x}[/tex]

Divide by 2

[tex]\mathbf{z = 2 - x}[/tex]

Substitute [tex]\mathbf{z = 2 - x}[/tex] in [tex]\mathbf{-x - y -z = -8}[/tex]

[tex]\mathbf{-x - y -z = -8}[/tex]

[tex]\mathbf{-x - y - (2-x) = -8}[/tex]

[tex]\mathbf{-x - y - 2+x = -8}[/tex]

Cancel out common terms

[tex]\mathbf{- y - 2 = -8}[/tex]

Add 2 to both sides

[tex]\mathbf{- y = -8+2}[/tex]

[tex]\mathbf{- y = -6}[/tex]

Divide by -1

[tex]\mathbf{y = 6}[/tex]

Substitute [tex]\mathbf{z = 2 - x}\mathbf{\ and\ y = 6}[/tex] in [tex]\mathbf{-4x + 4y +5z = 7}[/tex]

[tex]\mathbf{-4x + 4 \times 6 + 5 \times (2 - x) = 7}[/tex]

[tex]\mathbf{-4x + 24 + 5 \times (2 - x) = 7}[/tex]

Open brackets

[tex]\mathbf{-4x + 24 + 10 - 5x = 7}[/tex]

Collect like terms

[tex]\mathbf{-4x - 5x =- 24 - 10 + 7}[/tex]

[tex]\mathbf{-9x =-27}[/tex]

Divide through by -9

[tex]\mathbf{x =3}[/tex]

Recall that: [tex]\mathbf{z = 2 - x}[/tex]

So, we have:

[tex]\mathbf{z = 2-3}[/tex]

[tex]\mathbf{z = -1}[/tex]

Hence, the results are:

[tex]\mathbf{x =3}[/tex]

[tex]\mathbf{y = 6}[/tex]

[tex]\mathbf{z = -1}[/tex]

Answer:

[tex]\boxed {x = -19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3(-x - 3) + x - 3 = 26[/tex]

-Use Distributive Property:

[tex]3(-x - 3) + x - 3 = 26[/tex]

[tex]3(-x ) - 9 + x - 3 = 26[/tex]

-Combine both [tex]-9[/tex] and [tex]3[/tex]:

[tex]3(-x ) - 9 + x - 3 = 26[/tex]

[tex]3(-x ) - 12 + x = 26[/tex]

-Add [tex]12[/tex] to both sides:

[tex]3(-x ) - 12 + 12 + x = 26 + 12[/tex]

[tex]3(-x) + x = 38[/tex]

-Multiply the [tex]-1[/tex] by [tex]3[/tex]:

[tex]3(-x) + x = 38[/tex]

[tex]-3x + x = 38[/tex]

-Combine both the [tex]-3x[/tex] and [tex]x[/tex]:

[tex]-3x + x = 38[/tex]

[tex]-2x = 38[/tex]

-Divide both sides by [tex]-2[/tex]:

[tex]\frac{-2x}{-2} = \frac{38}{-2}[/tex]

[tex]\boxed {x = -19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].

______________________________

 [tex]\bold{Solution~Steps:}[/tex]

When we have a problem with parenthesis we must use distributive property:

         * [tex]3(-x)-9+x-3=26[/tex]

Subtract [tex]3[/tex] from [tex]-9[/tex]:

         * [tex]3(-x)-12+x=26[/tex]

Add [tex]12[/tex] to both sides:

         * [tex]3(-x)+x=38[/tex]

Multiply [tex]3[/tex] and [tex]-1[/tex]:

         * [tex]-3x+x=38[/tex]

Combine like terms:

         * [tex]-2x=38[/tex]

Divide to get [tex]x[/tex] alone:

        [tex]\boxed{x=-19}[/tex]

The reciprocal of 15/4 is 4/15.

Answer:

(13/24)

Step-by-step explanation:

let’s find a common number that we can get on the denominator

4 can be multiplied to get 48

6 can be multiplied to get 48

and 8 can also be multiplied to get 48

4(12) = 48

so for the equation (1/4) the numerator and denominator will both be multiplied by 12

(1/4)x(12/12) = (12/48)

6(8)= 48

(1/6)x(8/8) = (8/48)

8(6) = 48

(1/8)x(6/6) = (6/48)

now the fractions are

(12/48)+(8/48)+(6/48)

we can add them now because they have the same denominator and we get:

(26/48)

this can be simplified if we divide both the numerator and denominator by 2 and we get

(13/24)

Answer:

[tex]\frac{13}{24}[/tex]

Step-by-step explanation:

LCM(4, 6, 8) = 24

[tex]\frac{1}{4}[/tex] + [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{8}[/tex] = [tex]\frac{6+4+3}{24}[/tex] = [tex]\frac{13}{24}[/tex]

  x^2 +3x +2.25 = 12.25 . . . . add (3/2)² to complete the square

  (x +1.5)² = 3.5² . . . . write as squares

  x = -1.5 +3.5 . . . . . . take the positive square root*

* The negative square root gives an extraneous solution (x=-5).

I find that using a graphing calculator with the original equation avoids extraneous solutions. Here we transform the equation to the form f(x) = 0, so the x-intercept is the value of x we seek.

Given:

Consider the inequality is [tex]|x+3|<5[/tex] and its solution set is [tex]-8<x<2[/tex].

To find:

The statement that verify the solution set.

Solution:

Any value into the inequality form the solution set [tex]-8<x<2[/tex], will create a true statement and any value into the inequality not form the solution set [tex]-8<x<2[/tex], will create a false statement.

To verify the solution set set, we need to put any value form solution set into the given inequality.

Substituting a value into the inequality from the solution set, such as -2, will create a true statement.

Therefore, the correct option is A.

so since they are parrallel 8 is equal to 12 or you could do 9 is equal to 5 then you can see that they sit on the same straight line so angle9 + angle8 = 180 degrees
