Simplifying x + -5 * 3 = x + 9 Multiply -5 * 3 x + -15 = x + 9 Reorder the terms: -15 + x = x + 9 Reorder the terms: -15 + x = 9 + x Add '-1x' to each side of the equation. -15 + x + -1x = 9 + x + -1x Combine like terms: x + -1x = 0 -15 + 0 = 9 + x + -1x -15 = 9 + x + -1x Combine like terms: x + -1x = 0 -15 = 9 + 0 -15 = 9 Solving -15 = 9 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.
