Simplifying 9(11 + -1k) = 3(-3k + -9) (11 * 9 + -1k * 9) = 3(-3k + -9) (99 + -9k) = 3(-3k + -9) Reorder the terms: 99 + -9k = 3(-9 + -3k) 99 + -9k = (-9 * 3 + -3k * 3) 99 + -9k = (-27 + -9k) Add '9k' to each side of the equation. 99 + -9k + 9k = -27 + -9k + 9k Combine like terms: -9k + 9k = 0 99 + 0 = -27 + -9k + 9k 99 = -27 + -9k + 9k Combine like terms: -9k + 9k = 0 99 = -27 + 0 99 = -27 Solving 99 = -27 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.
