His work is shown below. 3 (x minus 1.25) = 11.25. 3 x minus 3.75 = 11.25. 3 x minus 3.75 + 3.75 = 11.25 + 3.75. 3 x = 15. 3 x times 3 = 45 times 3. x = 135. What mistake did Tobin make? Tobin did not distribute the 3 correctly. Tobin should have subtracted 3.75 from each side. Tobin should have divided by 3. Tobin did not make a mistake.
