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