Simplifying 4a + -1 = -2(-2a + 8) Reorder the terms: -1 + 4a = -2(-2a + 8) Reorder the terms: -1 + 4a = -2(8 + -2a) -1 + 4a = (8 * -2 + -2a * -2) -1 + 4a = (-16 + 4a) Add '-4a' to each side of the equation. -1 + 4a + -4a = -16 + 4a + -4a Combine like terms: 4a + -4a = 0 -1 + 0 = -16 + 4a + -4a -1 = -16 + 4a + -4a Combine like terms: 4a + -4a = 0 -1 = -16 + 0 -1 = -16 Solving -1 = -16 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.
