Simplifying 4(x + 1) = 2x + -7 + 2x Reorder the terms: 4(1 + x) = 2x + -7 + 2x (1 * 4 + x * 4) = 2x + -7 + 2x (4 + 4x) = 2x + -7 + 2x Reorder the terms: 4 + 4x = -7 + 2x + 2x Combine like terms: 2x + 2x = 4x 4 + 4x = -7 + 4x Add '-4x' to each side of the equation. 4 + 4x + -4x = -7 + 4x + -4x Combine like terms: 4x + -4x = 0 4 + 0 = -7 + 4x + -4x 4 = -7 + 4x + -4x Combine like terms: 4x + -4x = 0 4 = -7 + 0 4 = -7 Solving 4 = -7 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.
