Simplifying 7x + 8 = 7(x + 9) Reorder the terms: 8 + 7x = 7(x + 9) Reorder the terms: 8 + 7x = 7(9 + x) 8 + 7x = (9 * 7 + x * 7) 8 + 7x = (63 + 7x) Add '-7x' to each side of the equation. 8 + 7x + -7x = 63 + 7x + -7x Combine like terms: 7x + -7x = 0 8 + 0 = 63 + 7x + -7x 8 = 63 + 7x + -7x Combine like terms: 7x + -7x = 0 8 = 63 + 0 8 = 63 Solving 8 = 63 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.
