Simplifying 3x + -1x + -5 = 2(x + 4) + -9 Reorder the terms: -5 + 3x + -1x = 2(x + 4) + -9 Combine like terms: 3x + -1x = 2x -5 + 2x = 2(x + 4) + -9 Reorder the terms: -5 + 2x = 2(4 + x) + -9 -5 + 2x = (4 * 2 + x * 2) + -9 -5 + 2x = (8 + 2x) + -9 Reorder the terms: -5 + 2x = 8 + -9 + 2x Combine like terms: 8 + -9 = -1 -5 + 2x = -1 + 2x Add '-2x' to each side of the equation. -5 + 2x + -2x = -1 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 0 = -1 + 2x + -2x -5 = -1 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 = -1 + 0 -5 = -1 Solving -5 = -1 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.
