Simplifying 2x + -1(2x + 3) = 7 Reorder the terms: 2x + -1(3 + 2x) = 7 2x + (3 * -1 + 2x * -1) = 7 2x + (-3 + -2x) = 7 Reorder the terms: -3 + 2x + -2x = 7 Combine like terms: 2x + -2x = 0 -3 + 0 = 7 -3 = 7 Solving -3 = 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.
