Kimora Joseph · Answer 1

Simplify 6x + (x + - 2) = 180

6x + (-2 + x) = 180

Remove parenthesis around (-2 + x) 6x + - 2 + x = 180

Reorder - 2 + 6x + x = 180

Combine like terms: 6x + x = 7x - 2 + 7x = 180

-2 + 7x = 180

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

Add '2' to each side of the equation. - 2 + 2 + 7x = 180 + 2

Combine like terms: - 2 + 2 = 0 0 + 7x = 180 + 2 7x = 180 + 2

Combine like terms: 180 + 2 = 182 7x = 182

Divide each side by '7'. x = 26

Simplified answer x = 26

Simplifying 6x + (x + - 2) = 180

Reorder the terms: 6x + (-2 + x) = 180

Remove parenthesis around (-2 + x) 6x + - 2 + x = 180

Reorder the terms: - 2 + 6x + x = 180

Combine like terms: 6x + x = 7x - 2 + 7x = 180

Solving - 2 + 7x = 180

Solving for variable 'x'.

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

Add '2' to each side of the equation. - 2 + 2 + 7x = 180 + 2

Combine like terms: - 2 + 2 = 0 0 + 7x = 180 + 2 7x = 180 + 2

Combine like terms: 180 + 2 = 182 7x = 182

Divide each side by '7'. x = 26

Simplifying x = 26
