**Answer: ** In the last steps, instead of multiply each side by 3, he has to divide each side by 3.

**Step-by-step explanation:**

Hi, Tobin makes the mistake in the last steps.

3(x-1.25) = 11.25

3x-3.75= 11.25

3x-3.75+3.75= 11.25+3.75

3x = 15

Until this step is the work ok.

Now, instead of multiply each side by 3, he has to divide each side by 3:

So:

3x /3 = 15/3

x = 5
