Simplifying 2(x + -3) + 7 = 2x + 8 Reorder the terms: 2(-3 + x) + 7 = 2x + 8 (-3 * 2 + x * 2) + 7 = 2x + 8 (-6 + 2x) + 7 = 2x + 8 Reorder the terms: -6 + 7 + 2x = 2x + 8 Combine like terms: -6 + 7 = 1 1 + 2x = 2x + 8 Reorder the terms: 1 + 2x = 8 + 2x Add '-2x' to each side of the equation. 1 + 2x + -2x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 1 + 0 = 8 + 2x + -2x 1 = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 1 = 8 + 0 1 = 8 Solving 1 = 8 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.
