Simplifying -6 + -2(x + 7) = -2(x + 6) + -1 Reorder the terms: -6 + -2(7 + x) = -2(x + 6) + -1 -6 + (7 * -2 + x * -2) = -2(x + 6) + -1 -6 + (-14 + -2x) = -2(x + 6) + -1 Combine like terms: -6 + -14 = -20 -20 + -2x = -2(x + 6) + -1 Reorder the terms: -20 + -2x = -2(6 + x) + -1 -20 + -2x = (6 * -2 + x * -2) + -1 -20 + -2x = (-12 + -2x) + -1 Reorder the terms: -20 + -2x = -12 + -1 + -2x Combine like terms: -12 + -1 = -13 -20 + -2x = -13 + -2x Add '2x' to each side of the equation. -20 + -2x + 2x = -13 + -2x + 2x Combine like terms: -2x + 2x = 0 -20 + 0 = -13 + -2x + 2x -20 = -13 + -2x + 2x Combine like terms: -2x + 2x = 0 -20 = -13 + 0 -20 = -13 Solving -20 = -13 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.
