Simplifying 2(x + 2) + 7 = 6x + -4(-2 + x) Reorder the terms: 2(2 + x) + 7 = 6x + -4(-2 + x) (2 * 2 + x * 2) + 7 = 6x + -4(-2 + x) (4 + 2x) + 7 = 6x + -4(-2 + x) Reorder the terms: 4 + 7 + 2x = 6x + -4(-2 + x) Combine like terms: 4 + 7 = 11 11 + 2x = 6x + -4(-2 + x) 11 + 2x = 6x + (-2 * -4 + x * -4) 11 + 2x = 6x + (8 + -4x) Reorder the terms: 11 + 2x = 8 + 6x + -4x Combine like terms: 6x + -4x = 2x 11 + 2x = 8 + 2x Add '-2x' to each side of the equation. 11 + 2x + -2x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 11 + 0 = 8 + 2x + -2x 11 = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 11 = 8 + 0 11 = 8 Solving 11 = 8 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.
