Simplifying -10r + 1 = -10(r + 5) Reorder the terms: 1 + -10r = -10(r + 5) Reorder the terms: 1 + -10r = -10(5 + r) 1 + -10r = (5 * -10 + r * -10) 1 + -10r = (-50 + -10r) Add '10r' to each side of the equation. 1 + -10r + 10r = -50 + -10r + 10r Combine like terms: -10r + 10r = 0 1 + 0 = -50 + -10r + 10r 1 = -50 + -10r + 10r Combine like terms: -10r + 10r = 0 1 = -50 + 0 1 = -50 Solving 1 = -50 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.
