What is the answer to 3(4-3x) plus .5 (3-2)-3 (x-4)?

To solve the expression (3(4-3x) + 0.5(3-2) - 3(x-4)), first simplify each part: (3(4-3x) = 12 - 9x), (0.5(3-2) = 0.5), and (-3(x-4) = -3x + 12). Combining these gives (12 - 9x + 0.5 - 3x + 12 = 24.5 - 12x). Therefore, the final answer is (24.5 - 12x).
