Simplifying 7(x + x) = 5 + 2(7x + 6) Combine like terms: x + x = 2x 7(2x) = 5 + 2(7x + 6) Remove parenthesis around (2x) 7 * 2x = 5 + 2(7x + 6) Multiply 7 * 2 14x = 5 + 2(7x + 6) Reorder the terms: 14x = 5 + 2(6 + 7x) 14x = 5 + (6 * 2 + 7x * 2) 14x = 5 + (12 + 14x) Combine like terms: 5 + 12 = 17 14x = 17 + 14x Add '-14x' to each side of the equation. 14x + -14x = 17 + 14x + -14x Combine like terms: 14x + -14x = 0 0 = 17 + 14x + -14x Combine like terms: 14x + -14x = 0 0 = 17 + 0 0 = 17 Solving 0 = 17 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.
