Simplifying 7(x + -2) + 2 = 7x + -11 Reorder the terms: 7(-2 + x) + 2 = 7x + -11 (-2 * 7 + x * 7) + 2 = 7x + -11 (-14 + 7x) + 2 = 7x + -11 Reorder the terms: -14 + 2 + 7x = 7x + -11 Combine like terms: -14 + 2 = -12 -12 + 7x = 7x + -11 Reorder the terms: -12 + 7x = -11 + 7x Add '-7x' to each side of the equation. -12 + 7x + -7x = -11 + 7x + -7x Combine like terms: 7x + -7x = 0 -12 + 0 = -11 + 7x + -7x -12 = -11 + 7x + -7x Combine like terms: 7x + -7x = 0 -12 = -11 + 0 -12 = -11 Solving -12 = -11 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.
