Simplifying -2r + 1 = 7(2r + -7) + -8(-7 + 2r) Reorder the terms: 1 + -2r = 7(2r + -7) + -8(-7 + 2r) Reorder the terms: 1 + -2r = 7(-7 + 2r) + -8(-7 + 2r) 1 + -2r = (-7 * 7 + 2r * 7) + -8(-7 + 2r) 1 + -2r = (-49 + 14r) + -8(-7 + 2r) 1 + -2r = -49 + 14r + (-7 * -8 + 2r * -8) 1 + -2r = -49 + 14r + (56 + -16r) Reorder the terms: 1 + -2r = -49 + 56 + 14r + -16r Combine like terms: -49 + 56 = 7 1 + -2r = 7 + 14r + -16r Combine like terms: 14r + -16r = -2r 1 + -2r = 7 + -2r Add '2r' to each side of the equation. 1 + -2r + 2r = 7 + -2r + 2r Combine like terms: -2r + 2r = 0 1 + 0 = 7 + -2r + 2r 1 = 7 + -2r + 2r Combine like terms: -2r + 2r = 0 1 = 7 + 0 1 = 7 Solving 1 = 7 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.
