Option E contains the incorrect solution. If we simplify the equation t - 2t - 3t = 32, it combines to -4t = 32. Solving for t, we divide both sides by -4 to get t = -8, not 8. Therefore, the solution provided in option E is incorrect.
The correct question is A. 2x + 5(x - 1) = 9, x = 2 B. p - 3(p - 5) = 10, p = 2.5 C. 4y + 3 y = 28, y = 4 D. 5w + 6w - 3w = 64, w = 8 E. t - 2t - 3t = 32, t = 8
