Order equivalent equations of 6(h−4) = 3h to solve for h.
Answers
Answer:
8
Step-by-step explanation:
6h-24=3h
-24=-3h
divide both sides by negative 3
8 = h
The solution for the given equation is h=8.
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is 6(h-4)=3h.
The given equation can be solved as follows
6(h-4)=3h
⇒ 6h-24=3h
⇒ 6h-3h=24
⇒ 3h=24
⇒ h=24/3
⇒ h=8
Therefore, the solution for the given equation is h=8.

-2(x -5) = -16
can someone please answer this asap

Answer:
x = 13
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](-2)(x) + (-2)(-5)= -16[/tex] [tex]-2x + 10 =-16[/tex]Step 2: Subtract 10 from both sides.
[tex]-2x + 10 - 10 = -16 - 10[/tex] [tex]-2x = -26[/tex]Step 3: Divide both sides by -2.
[tex]\frac{-2x}{-2}=\frac{-26}{-2}[/tex] [tex]x = 13[/tex]Step 4: Check if solution is correct.
[tex]-2(13-5)=-16[/tex] [tex]-26 + 10 = -16[/tex] [tex]-16=-16[/tex]Therefore, x = 13.
Answer:
x=13
Step-by-step explanation:
-2(x -5) = -16
Divide each side by -2
-2(x -5)/-2 = -16/-2
x-5 = 8
Add 5 to each side
x-5+5 = 8+5

which of the following doesnot represent pair of integers (a,b) such that a÷b=3
Answers
Explanation
a divided by b = 3
it’s (a,b) so a is out x value and b is the y value, so it’s x divided by y
(-9, 3) ❌
In this case our x is -9 and y is 3
-9 divided by 3 = -3
If the 3 was negative, this would work
(15,-1) ❌
Now our x is -15 and our y is -1
-15 divided by -1 = 15
If it was -3 instead of -1 this would work
(6,2) ✔️
Now x is 6 and y is 2
6 divided by 2 = 3
So this works
(-3, -1) ✔️
Now x is -3 and y is -1
-3 divided by -1 = 3
So this also works
