Simplifying (7X + 2) = (7X + 9) Reorder the terms: (2 + 7X) = (7X + 9) Remove parenthesis around (2 + 7X) 2 + 7X = (7X + 9) Reorder the terms: 2 + 7X = (9 + 7X) Remove parenthesis around (9 + 7X) 2 + 7X = 9 + 7X Add '-7X' to each side of the equation. 2 + 7X + -7X = 9 + 7X + -7X Combine like terms: 7X + -7X = 0 2 + 0 = 9 + 7X + -7X 2 = 9 + 7X + -7X Combine like terms: 7X + -7X = 0 2 = 9 + 0 2 = 9 Solving 2 = 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.
