**Answer:**

1st question: $1.68

2nd question: x=3.6

**Step-by-step explanation:**

**1st: 6.72/4=1.68**

**2nd: 3.2x/3.2 = 11.52/3.2**

**11.52/3.2=3.6**

**Remark**

This is confusing. You don't quite know what to do about that two. "They" shouldn't do that to beginners. The order that you do things is brackets, then division. The addition comes last. When I saw the question typed out, I thought it was 24/5 just as you did.

The typed expression makes it clearer. So lets solve it.

**Solve**

8 + 2 is the answer.

10
