Simplifying 2(1 + -2k) = 4(2 + -1k) (1 * 2 + -2k * 2) = 4(2 + -1k) (2 + -4k) = 4(2 + -1k) 2 + -4k = (2 * 4 + -1k * 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.
