Simplifying 9x + 4 = 9(x + -3) Reorder the terms: 4 + 9x = 9(x + -3) Reorder the terms: 4 + 9x = 9(-3 + x) 4 + 9x = (-3 * 9 + x * 9) 4 + 9x = (-27 + 9x) Add '-9x' to each side of the equation. 4 + 9x + -9x = -27 + 9x + -9x Combine like terms: 9x + -9x = 0 4 + 0 = -27 + 9x + -9x 4 = -27 + 9x + -9x Combine like terms: 9x + -9x = 0 4 = -27 + 0 4 = -27 Solving 4 = -27 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.
