Well..... Mate your answer is here

x-90+x-(+x)

Simplifying

90 + x + 2x = 180

Combine like terms: x + 2x = 3x

90 + 3x = 180

Solving

90 + 3x = 180

Solving for variable 'x'.

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

Add '-90' to each side of the equation.

90 + -90 + 3x = 180 + -90

Combine like terms: 90 + -90 = 0

0 + 3x = 180 + -90

3x = 180 + -90

Combine like terms: 180 + -90 = 90

3x = 90

Divide each side by '3'.

x = 30

Simplifying

x = 30
