Simplifying 1.8d + 2 = 2(0.9d + -1.5) Reorder the terms: 2 + 1.8d = 2(0.9d + -1.5) Reorder the terms: 2 + 1.8d = 2(-1.5 + 0.9d) 2 + 1.8d = (-1.5 * 2 + 0.9d * 2) 2 + 1.8d = (-3 + 1.8d) Add '-1.8d' to each side of the equation. 2 + 1.8d + -1.8d = -3 + 1.8d + -1.8d Combine like terms: 1.8d + -1.8d = 0.0 2 + 0.0 = -3 + 1.8d + -1.8d 2 = -3 + 1.8d + -1.8d Combine like terms: 1.8d + -1.8d = 0.0 2 = -3 + 0.0 2 = -3 Solving 2 = -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.
