Simplifying 13x + -1 = 1 + 13x Reorder the terms: -1 + 13x = 1 + 13x Add '-13x' to each side of the equation. -1 + 13x + -13x = 1 + 13x + -13x Combine like terms: 13x + -13x = 0 -1 + 0 = 1 + 13x + -13x -1 = 1 + 13x + -13x Combine like terms: 13x + -13x = 0 -1 = 1 + 0 -1 = 1 Solving -1 = 1 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.
