Simplifying 4.2x + -3 = 0.5(8.4x + 6) Reorder the terms: -3 + 4.2x = 0.5(8.4x + 6) Reorder the terms: -3 + 4.2x = 0.5(6 + 8.4x) -3 + 4.2x = (6 * 0.5 + 8.4x * 0.5) -3 + 4.2x = (3 + 4.2x) Add '-4.2x' to each side of the equation. -3 + 4.2x + -4.2x = 3 + 4.2x + -4.2x Combine like terms: 4.2x + -4.2x = 0.0 -3 + 0.0 = 3 + 4.2x + -4.2x -3 = 3 + 4.2x + -4.2x Combine like terms: 4.2x + -4.2x = 0.0 -3 = 3 + 0.0 -3 = 3 Solving -3 = 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.
