Simplifying 7(x + 9) + 2 = 7x + 3 Reorder the terms: 7(9 + x) + 2 = 7x + 3 (9 * 7 + x * 7) + 2 = 7x + 3 (63 + 7x) + 2 = 7x + 3 Reorder the terms: 63 + 2 + 7x = 7x + 3 Combine like terms: 63 + 2 = 65 65 + 7x = 7x + 3 Reorder the terms: 65 + 7x = 3 + 7x Add '-7x' to each side of the equation. 65 + 7x + -7x = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 65 + 0 = 3 + 7x + -7x 65 = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 65 = 3 + 0 65 = 3 Solving 65 = 3 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.
