Simplifying -2x + 4 + -5x + -5 = -9x + 2x + 2 Reorder the terms: 4 + -5 + -2x + -5x = -9x + 2x + 2 Combine like terms: 4 + -5 = -1 -1 + -2x + -5x = -9x + 2x + 2 Combine like terms: -2x + -5x = -7x -1 + -7x = -9x + 2x + 2 Reorder the terms: -1 + -7x = 2 + -9x + 2x Combine like terms: -9x + 2x = -7x -1 + -7x = 2 + -7x Add '7x' to each side of the equation. -1 + -7x + 7x = 2 + -7x + 7x Combine like terms: -7x + 7x = 0 -1 + 0 = 2 + -7x + 7x -1 = 2 + -7x + 7x Combine like terms: -7x + 7x = 0 -1 = 2 + 0 -1 = 2 Solving -1 = 2 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.
