Answer:
Subtract y from both sides of the equation.
x=8−y
2x+2y=16
Replace all occurrences of x with 8−y in each equation.
16=16
x=8−y
Remove any equations from the system that are always true.
x=8−y

Step-by-step explanation:
Jane multiplies her number by three and subtracts 2.
Elliot multiplies his number by 2 and adds 3.
When they multiply their results together, the product is 110.
They both chose the same number to start with. What was their number?
Answer:
Let the number they chose be 'x'.
Result of Jane = [tex]3x -2[/tex]
Result of Elliot = [tex]2x+3[/tex]
Given that,
The product of their result = 110
[tex]or, (3x-2)(2x+3) = 110\\or, 6x^{2} +9x-4x-6 = 110\\or, 6x^{2} +5x - 6 = 110\\or, 6x^{2} +5x - 6-110 = 0\\\\or, 6x^{2} +5x - 116 = 0\\or, 6x^{2} +29x - 24x - 116 = 0\\or, x (6x +29) -4(6x+29) = 0\\or, (x-4)(6x+29) = 0\\i.e. x=4 or x=\frac{-29}{6} \\So,~ the ~number ~they~ chose~was ~either ~4 ~or ~\frac{-29}{6}[/tex]

x + 2x + 3 + 3 = 3(x + 2)
Answer:
x = 3
Step-by-step explanation:
cuz x + 2x + 3 + 3 = 3(x+2)
replace x with 3
3 + 2(3) + 3 + 3 = 3(3+2)
3 + 2(3) = 9 + 3 = 12 + 3 = 15
3(3+2) = 15
Pls can i be brainliest...
Answer:
Step-by-step explanation:
x + 2x + 3 + 3 = 3(x + 2)
Do the distributive property
x + 2x + 3 + 3 = 3 * x + 3 * 2
x + 2x + 3 + 3 = 3x + 6
Combine like terms
3x + 6 = 3x + 6
Subtract 6 on both sides
3x + 6 - 6 = 3x + 6 - 6
3x = 3x
As you can see, they are the same...which means
Any value of x makes the equation true. All real numbers
1, 2, 3 , 4 etc
Any value u put into the equation to represent "x" will be true...
EX:
3x = 3x
( if x were 7 we substitute that)
3(7) = 3 (7)
21 = 21 CORRECT
They will be the same answer/ have the same value.

Answer:
Elizabeth had 30 stamps originally.
Step-by-step explanation:
Let,
x be the number of stamps Elizabeth have.
Number of stamps given to John = 1/6 of x = [tex]\frac{1}{6}x[/tex]
Remaining stamps = [tex]x-\frac{1}{6}x = \frac{6x-1x}{6} = \frac{5}{6}x[/tex]
Stamps given to Peter = 1/5 of remainder = [tex]\frac{1}{5}*\frac{5}{6}x = \frac{1}{6}x[/tex]
Number of stamps left = 20
Now,
[tex]\frac{1}{6}x + \frac{1}{6}x + 20 = x\\\\\frac{1x+1x+120}{6} = x\\\\\frac{2x+120}{6} = x\\\\2x + 120 = 6x \\\\120 = 6x - 2x \\\\120 = 4x \\4x = 120[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{120}{4}\\x=30[/tex]
Hence,
Elizabeth had 30 stamps originally.

Answer:
a.) 0.671
b.) 0.985
c.) 0.137
Step-by-step explanation:
Ok..this is easy when you do it a specific way....
a.)
You can easily do 5 - 4.329 and it will give you 0.671.
Now you can do 5 - 0.671 and it will give you the answer as 4.329.
And you got your answer.
The missing value for equation a = 0.671.
b.)
You can easily do 1 - 0.015 and it will give you 0.985.
Now you can do 1 - 0.985 and it will give you the answer as 0.015.
And you got your answer.
The missing vaule for equation b = 0.985.
c.)
You can easily do 1 - 0.863 and it will give you 0.137.
Now you can do 1 - 0.137 and it will give you the answer as 0.863.
And you got your answer.
The missing value for equation c = 0.137
All you have to do is subtract the first number they gave you (the top one), with the actual answer the give you (at the bottom)

Answer:
1. 3 + 4 = 7 (they gave m already)
2. 9 - 4 = 5 (they gave both m and z)
3. 12 * 1/6 = 12/6 = 2 (they gave r)
4. 4(4) - 2 = 16 - 2 = 14 (they gave m)
5. 60 1/6 - 4 = 60/6 - 4 = 10 - 4 = 6
6. 3 1/6 * 1/6 = 3 * 1/12 = 3/12 = 1/4
All you have to do is substitute the variable with what they gave to u as a value
