Simplifying 2(a + -1) = 2a + 3 Reorder the terms: 2(-1 + a) = 2a + 3 (-1 * 2 + a * 2) = 2a + 3 (-2 + 2a) = 2a + 3 Reorder the terms: -2 + 2a = 3 + 2a Add '-2a' to each side of the equation. -2 + 2a + -2a = 3 + 2a + -2a Combine like terms: 2a + -2a = 0 -2 + 0 = 3 + 2a + -2a -2 = 3 + 2a + -2a Combine like terms: 2a + -2a = 0 -2 = 3 + 0 -2 = 3 Solving -2 = 3 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.
