Simplifying x + 2 * 2 = x + 13 Multiply 2 * 2 x + 4 = x + 13 Reorder the terms: 4 + x = x + 13 Reorder the terms: 4 + x = 13 + x Add '-1x' to each side of the equation. 4 + x + -1x = 13 + x + -1x Combine like terms: x + -1x = 0 4 + 0 = 13 + x + -1x 4 = 13 + x + -1x Combine like terms: x + -1x = 0 4 = 13 + 0 4 = 13 Solving 4 = 13 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.
