Simplifying 12x + -8 + 2x = 7(2x + 1) Reorder the terms: -8 + 12x + 2x = 7(2x + 1) Combine like terms: 12x + 2x = 14x -8 + 14x = 7(2x + 1) Reorder the terms: -8 + 14x = 7(1 + 2x) -8 + 14x = (1 * 7 + 2x * 7) -8 + 14x = (7 + 14x) Add '-14x' to each side of the equation. -8 + 14x + -14x = 7 + 14x + -14x Combine like terms: 14x + -14x = 0 -8 + 0 = 7 + 14x + -14x -8 = 7 + 14x + -14x Combine like terms: 14x + -14x = 0 -8 = 7 + 0 -8 = 7 Solving -8 = 7 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.
