Simplifying x + 13 = x + -21 Reorder the terms: 13 + x = x + -21 Reorder the terms: 13 + x = -21 + x Add '-1x' to each side of the equation. 13 + x + -1x = -21 + x + -1x Combine like terms: x + -1x = 0 13 + 0 = -21 + x + -1x 13 = -21 + x + -1x Combine like terms: x + -1x = 0 13 = -21 + 0 13 = -21 Solving 13 = -21 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.
