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