Simplifying -12 + -2k = -2(k + 4) Reorder the terms: -12 + -2k = -2(4 + k) -12 + -2k = (4 * -2 + k * -2) -12 + -2k = (-8 + -2k) Add '2k' to each side of the equation. -12 + -2k + 2k = -8 + -2k + 2k Combine like terms: -2k + 2k = 0 -12 + 0 = -8 + -2k + 2k -12 = -8 + -2k + 2k Combine like terms: -2k + 2k = 0 -12 = -8 + 0 -12 = -8 Solving -12 = -8 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.
