How to solve 10-3 (3x-40) = - 9x

Simplifying 10 + - 3 (3x + - 40) = - 9x

Reorder the terms: 10 + - 3 (-40 + 3x) = - 9x

10 + (-40 * - 3 + 3x * - 3) = - 9x

10 + (120 + - 9x) = - 9x

Combine like terms: 10 + 120 = 130 130 + - 9x = - 9x

Add '9x' to each side of the equation. 130 + - 9x + 9x = - 9x + 9x

Combine like terms: - 9x + 9x = 0 130 + 0 = - 9x + 9x 130 = - 9x + 9x

Combine like terms: - 9x + 9x = 0 130 = 0

Solving 130 = 0
