Simplifying 2a + 8 = 2a + -4 Reorder the terms: 8 + 2a = 2a + -4 Reorder the terms: 8 + 2a = -4 + 2a Add '-2a' to each side of the equation. 8 + 2a + -2a = -4 + 2a + -2a Combine like terms: 2a + -2a = 0 8 + 0 = -4 + 2a + -2a 8 = -4 + 2a + -2a Combine like terms: 2a + -2a = 0 8 = -4 + 0 8 = -4 Solving 8 = -4 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.
