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