x+3/3=y+2/2 the left side needs to look like x/3 First we want to isolate x on the left side. What should we do?

2. anonymous

i dont understand

3. anonymous

Do you know how to multiply?

4. anonymous

yes

5. anonymous

Multiply both sides by 3

6. anonymous

9

7. anonymous

lol you don't know how to multiply?

8. anonymous

Well let's do an easier one first # 3 4/9=m/54 $\frac{4}{9}=\frac{m}{54}$

9. anonymous

Multiply both sides by 54 in order to isolate m on the right side. Can you tell me what you get for m?

10. anonymous

so 54 *4 and 9

11. anonymous

yes $\frac{54*4}{9}=m$ can you simplify that?

12. anonymous

486/9=m

13. anonymous

54=m

14. anonymous

How did you get 486?

15. anonymous

54*4

16. anonymous

No that doesn't sound right. Do it again.
