Simplifying 2(a + 1) + -5 = 2a Reorder the terms: 2(1 + a) + -5 = 2a (1 * 2 + a * 2) + -5 = 2a (2 + 2a) + -5 = 2a Reorder the terms: 2 + -5 + 2a = 2a Combine like terms: 2 + -5 = -3 -3 + 2a = 2a Add '-2a' to each side of the equation. -3 + 2a + -2a = 2a + -2a Combine like terms: 2a + -2a = 0 -3 + 0 = 2a + -2a -3 = 2a + -2a Combine like terms: 2a + -2a = 0 -3 = 0 Solving -3 = 0 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.
