Simplifying -2(x + 3) = 5x + -7x + -7 Reorder the terms: -2(3 + x) = 5x + -7x + -7 (3 * -2 + x * -2) = 5x + -7x + -7 (-6 + -2x) = 5x + -7x + -7 Reorder the terms: -6 + -2x = -7 + 5x + -7x Combine like terms: 5x + -7x = -2x -6 + -2x = -7 + -2x Add '2x' to each side of the equation. -6 + -2x + 2x = -7 + -2x + 2x Combine like terms: -2x + 2x = 0 -6 + 0 = -7 + -2x + 2x -6 = -7 + -2x + 2x Combine like terms: -2x + 2x = 0 -6 = -7 + 0 -6 = -7 Solving -6 = -7 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.
