Simplifying r + -4(2) = r + 6 Multiply -4 * 2 r + -8 = r + 6 Reorder the terms: -8 + r = r + 6 Reorder the terms: -8 + r = 6 + r Add '-1r' to each side of the equation. -8 + r + -1r = 6 + r + -1r Combine like terms: r + -1r = 0 -8 + 0 = 6 + r + -1r -8 = 6 + r + -1r Combine like terms: r + -1r = 0 -8 = 6 + 0 -8 = 6 Solving -8 = 6 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.
