Answer 1

1. Question isn't complete. It says "Which gives the first two steps to evaluate" and cuts off.

2. Seems like 3.(4-2)2+1 if 3. means to multiply.

3. 9.1=9 should be the answer if . means to multiply.

4. 10x+0=10x

5. x=3 or y=-8

6. x=5 or y=-6

7. Not so sure about this one.

8. 7x/9y

9. 5

Explanation:

2. 3.(4-2)2+1

3(2)2+1

6(2)+1
