Simplifying 2x2 + 40 = 2x2 + 56 Reorder the terms: 40 + 2x2 = 2x2 + 56 Reorder the terms: 40 + 2x2 = 56 + 2x2 Add '-2x2' to each side of the equation. 40 + 2x2 + -2x2 = 56 + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 40 + 0 = 56 + 2x2 + -2x2 40 = 56 + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 40 = 56 + 0 40 = 56 Solving 40 = 56 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.
