Simplifying 2x + -4(x + 1) = -2x + 16 Reorder the terms: 2x + -4(1 + x) = -2x + 16 2x + (1 * -4 + x * -4) = -2x + 16 2x + (-4 + -4x) = -2x + 16 Reorder the terms: -4 + 2x + -4x = -2x + 16 Combine like terms: 2x + -4x = -2x -4 + -2x = -2x + 16 Reorder the terms: -4 + -2x = 16 + -2x Add '2x' to each side of the equation. -4 + -2x + 2x = 16 + -2x + 2x Combine like terms: -2x + 2x = 0 -4 + 0 = 16 + -2x + 2x -4 = 16 + -2x + 2x Combine like terms: -2x + 2x = 0 -4 = 16 + 0 -4 = 16 Solving -4 = 16 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.
