Simplifying 2(x + 3) + -7x = -5(x + 4) Reorder the terms: 2(3 + x) + -7x = -5(x + 4) (3 * 2 + x * 2) + -7x = -5(x + 4) (6 + 2x) + -7x = -5(x + 4) Combine like terms: 2x + -7x = -5x 6 + -5x = -5(x + 4) Reorder the terms: 6 + -5x = -5(4 + x) 6 + -5x = (4 * -5 + x * -5) 6 + -5x = (-20 + -5x) Add '5x' to each side of the equation. 6 + -5x + 5x = -20 + -5x + 5x Combine like terms: -5x + 5x = 0 6 + 0 = -20 + -5x + 5x 6 = -20 + -5x + 5x Combine like terms: -5x + 5x = 0 6 = -20 + 0 6 = -20 Solving 6 = -20 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.
