Simplifying 4(x + -3) + 9 = 2x + 2(-2 + x) Reorder the terms: 4(-3 + x) + 9 = 2x + 2(-2 + x) (-3 * 4 + x * 4) + 9 = 2x + 2(-2 + x) (-12 + 4x) + 9 = 2x + 2(-2 + x) Reorder the terms: -12 + 9 + 4x = 2x + 2(-2 + x) Combine like terms: -12 + 9 = -3 -3 + 4x = 2x + 2(-2 + x) -3 + 4x = 2x + (-2 * 2 + x * 2) -3 + 4x = 2x + (-4 + 2x) Reorder the terms: -3 + 4x = -4 + 2x + 2x Combine like terms: 2x + 2x = 4x -3 + 4x = -4 + 4x Add '-4x' to each side of the equation. -3 + 4x + -4x = -4 + 4x + -4x Combine like terms: 4x + -4x = 0 -3 + 0 = -4 + 4x + -4x -3 = -4 + 4x + -4x Combine like terms: 4x + -4x = 0 -3 = -4 + 0 -3 = -4 Solving -3 = -4 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
