Simplifying 9 + -2(2x + 5) = 27 + -4x Reorder the terms: 9 + -2(5 + 2x) = 27 + -4x 9 + (5 * -2 + 2x * -2) = 27 + -4x 9 + (-10 + -4x) = 27 + -4x Combine like terms: 9 + -10 = -1 -1 + -4x = 27 + -4x Add '4x' to each side of the equation. -1 + -4x + 4x = 27 + -4x + 4x Combine like terms: -4x + 4x = 0 -1 + 0 = 27 + -4x + 4x -1 = 27 + -4x + 4x Combine like terms: -4x + 4x = 0 -1 = 27 + 0 -1 = 27 Solving -1 = 27 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.
