Answer 2

Step-by-step explanation:

Simplifying

9 = 7x + 16

Reorder the terms:

9 = 16 + 7x

Solving

9 = 16 + 7x

Solving for variable 'x'.

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

Add '-7x' to each side of the equation.

9 + -7x = 16 + 7x + -7x

Combine like terms: 7x + -7x = 0

9 + -7x = 16 + 0

9 + -7x = 16

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

9 + -9 + -7x = 16 + -9

Combine like terms: 9 + -9 = 0

0 + -7x = 16 + -9

-7x = 16 + -9

Combine like terms: 16 + -9 = 7

-7x = 7

Divide each side by '-7'.

x = -1

Simplifying

x = -1
