Simplifying (2x + 20) = (2x + -45) Reorder the terms: (20 + 2x) = (2x + -45) Remove parenthesis around (20 + 2x) 20 + 2x = (2x + -45) Reorder the terms: 20 + 2x = (-45 + 2x) Remove parenthesis around (-45 + 2x) 20 + 2x = -45 + 2x Add '-2x' to each side of the equation. 20 + 2x + -2x = -45 + 2x + -2x Combine like terms: 2x + -2x = 0 20 + 0 = -45 + 2x + -2x 20 = -45 + 2x + -2x Combine like terms: 2x + -2x = 0 20 = -45 + 0 20 = -45 Solving 20 = -45 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.
