Answer 2

X = 7

Explanation:

Simplifying

7x + -9 + 4x + 22 = 90

Reorder the terms:

-9 + 22 + 7x + 4x = 90

Combine like terms: -9 + 22 = 13

13 + 7x + 4x = 90

Combine like terms: 7x + 4x = 11x

13 + 11x = 90

Solving

13 + 11x = 90

Solving for variable 'x'.

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

Add '-13' to each side of the equation.

13 + -13 + 11x = 90 + -13

Combine like terms: 13 + -13 = 0

0 + 11x = 90 + -13

11x = 90 + -13

Combine like terms: 90 + -13 = 77

11x = 77

Divide each side by '11'.

x = 7

Simplifying

x = 7
