Simplifying 13(x + 4) = 13x + 4 Reorder the terms: 13(4 + x) = 13x + 4 (4 * 13 + x * 13) = 13x + 4 (52 + 13x) = 13x + 4 Reorder the terms: 52 + 13x = 4 + 13x Add '-13x' to each side of the equation. 52 + 13x + -13x = 4 + 13x + -13x Combine like terms: 13x + -13x = 0 52 + 0 = 4 + 13x + -13x 52 = 4 + 13x + -13x Combine like terms: 13x + -13x = 0 52 = 4 + 0 52 = 4 Solving 52 = 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.
