Simplifying -2(x + -7) = -0.5(4x + -7) Reorder the terms: -2(-7 + x) = -0.5(4x + -7) (-7 * -2 + x * -2) = -0.5(4x + -7) (14 + -2x) = -0.5(4x + -7) Reorder the terms: 14 + -2x = -0.5(-7 + 4x) 14 + -2x = (-7 * -0.5 + 4x * -0.5) 14 + -2x = (3.5 + -2x) Add '2x' to each side of the equation. 14 + -2x + 2x = 3.5 + -2x + 2x Combine like terms: -2x + 2x = 0 14 + 0 = 3.5 + -2x + 2x 14 = 3.5 + -2x + 2x Combine like terms: -2x + 2x = 0 14 = 3.5 + 0 14 = 3.5 Solving 14 = 3.5 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.
