Simplifying 2(x + 7) = -8 + 28 + 2x Reorder the terms: 2(7 + x) = -8 + 28 + 2x (7 * 2 + x * 2) = -8 + 28 + 2x (14 + 2x) = -8 + 28 + 2x Combine like terms: -8 + 28 = 20 14 + 2x = 20 + 2x Add '-2x' to each side of the equation. 14 + 2x + -2x = 20 + 2x + -2x Combine like terms: 2x + -2x = 0 14 + 0 = 20 + 2x + -2x 14 = 20 + 2x + -2x Combine like terms: 2x + -2x = 0 14 = 20 + 0 14 = 20 Solving 14 = 20 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.
