Simplifying 2(2k + 1) = 4(k + -2) Reorder the terms: 2(1 + 2k) = 4(k + -2) (1 * 2 + 2k * 2) = 4(k + -2) (2 + 4k) = 4(k + -2) Reorder the terms: 2 + 4k = 4(-2 + k) 2 + 4k = (-2 * 4 + k * 4) 2 + 4k = (-8 + 4k) Add '-4k' to each side of the equation. 2 + 4k + -4k = -8 + 4k + -4k Combine like terms: 4k + -4k = 0 2 + 0 = -8 + 4k + -4k 2 = -8 + 4k + -4k Combine like terms: 4k + -4k = 0 2 = -8 + 0 2 = -8 Solving 2 = -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.
