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