Simplifying 7(-1x + -2) = -7x + 7 Reorder the terms: 7(-2 + -1x) = -7x + 7 (-2 * 7 + -1x * 7) = -7x + 7 (-14 + -7x) = -7x + 7 Reorder the terms: -14 + -7x = 7 + -7x Add '7x' to each side of the equation. -14 + -7x + 7x = 7 + -7x + 7x Combine like terms: -7x + 7x = 0 -14 + 0 = 7 + -7x + 7x -14 = 7 + -7x + 7x Combine like terms: -7x + 7x = 0 -14 = 7 + 0 -14 = 7 Solving -14 = 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.
