Simplifying 3x + -5 = 2(2x + -4) + -1x Reorder the terms: -5 + 3x = 2(2x + -4) + -1x Reorder the terms: -5 + 3x = 2(-4 + 2x) + -1x -5 + 3x = (-4 * 2 + 2x * 2) + -1x -5 + 3x = (-8 + 4x) + -1x Combine like terms: 4x + -1x = 3x -5 + 3x = -8 + 3x Add '-3x' to each side of the equation. -5 + 3x + -3x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -5 + 0 = -8 + 3x + -3x -5 = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -5 = -8 + 0 -5 = -8 Solving -5 = -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.
