Simplifying -7x = -9(x + -3) + 2x Reorder the terms: -7x = -9(-3 + x) + 2x -7x = (-3 * -9 + x * -9) + 2x -7x = (27 + -9x) + 2x Combine like terms: -9x + 2x = -7x -7x = 27 + -7x Add '7x' to each side of the equation. -7x + 7x = 27 + -7x + 7x Combine like terms: -7x + 7x = 0 0 = 27 + -7x + 7x Combine like terms: -7x + 7x = 0 0 = 27 + 0 0 = 27 Solving 0 = 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.
