Simplifying 2(3d + 3) = 7 + 6d Reorder the terms: 2(3 + 3d) = 7 + 6d (3 * 2 + 3d * 2) = 7 + 6d (6 + 6d) = 7 + 6d Add '-6d' to each side of the equation. 6 + 6d + -6d = 7 + 6d + -6d Combine like terms: 6d + -6d = 0 6 + 0 = 7 + 6d + -6d 6 = 7 + 6d + -6d Combine like terms: 6d + -6d = 0 6 = 7 + 0 6 = 7 Solving 6 = 7 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.
