Simplifying 2(x + -3) + -1 = 4x + -2(1 + x) Reorder the terms: 2(-3 + x) + -1 = 4x + -2(1 + x) (-3 * 2 + x * 2) + -1 = 4x + -2(1 + x) (-6 + 2x) + -1 = 4x + -2(1 + x) Reorder the terms: -6 + -1 + 2x = 4x + -2(1 + x) Combine like terms: -6 + -1 = -7 -7 + 2x = 4x + -2(1 + x) -7 + 2x = 4x + (1 * -2 + x * -2) -7 + 2x = 4x + (-2 + -2x) Reorder the terms: -7 + 2x = -2 + 4x + -2x Combine like terms: 4x + -2x = 2x -7 + 2x = -2 + 2x Add '-2x' to each side of the equation. -7 + 2x + -2x = -2 + 2x + -2x Combine like terms: 2x + -2x = 0 -7 + 0 = -2 + 2x + -2x -7 = -2 + 2x + -2x Combine like terms: 2x + -2x = 0 -7 = -2 + 0 -7 = -2 Solving -7 = -2 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.
