Question

What is the variable of 72=9x+9

Answer 1

x=7

Explanation:

Simplifying

9x + 9 = 72

Reorder the terms:

9 + 9x = 72

Solving

9 + 9x = 72

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + 9x = 72 + -9

Combine like terms: 9 + -9 = 0

0 + 9x = 72 + -9

9x = 72 + -9

Combine like terms: 72 + -9 = 63

9x = 63

Divide each side by '9'.

x = 7

Simplifying

x = 7

hope this helps :D

Answer 2

x = 7

Subtract 9 from both sides of the equation. Your equation should then look like 63 = 9x. Next, divide both sides by 9 to get the variable by itself. 63 divided by 9 is 7. Therefore, x = 7.
