do i simplfy ?

3. JenniferSmart1 Group Title

you would need common denominators, before you do anything. Do you know how to do that? I can walk you through it if you're not familiar with that

4. rawrrainbowsz2 Group Title

yea one min

6. JenniferSmart1 Group Title

almost So it's $\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}$ because $\frac44\cdot \frac{1}{3}y+\frac33 \cdot \frac{1}{4}=\frac{5}{12}$

7. JenniferSmart1 Group Title

does that make sense?

8. rawrrainbowsz2 Group Title

so 5/12 stays the same ?

9. JenniferSmart1 Group Title

yes because it already has the common denominator of 12. We're trying to make it so that all the numbers have 12 on the bottom

10. JenniferSmart1 Group Title

now we can solve for y

11. rawrrainbowsz2 Group Title

ok im re writing it

13. rawrrainbowsz2 Group Title

i got stuck

14. JenniferSmart1 Group Title

$\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}$ ok now we need to get $\frac3{12}$ over to the right hand side of the equal sign so subtract $\frac3{12}$ from both sides $\frac{4}{12}y+\cancel{\frac{3}{12}-\frac3{12}}=\frac{5}{12}-\frac3{12}$

15. rawrrainbowsz2 Group Title

4/12y =2/12

16. JenniferSmart1 Group Title

yes!

17. JenniferSmart1 Group Title

now we need to get the y out of the denominator. do you know how to do that?

18. rawrrainbowsz2 Group Title

multiply ?

19. JenniferSmart1 Group Title

wait, is y in the denominator or is it just like this: $\frac4{12}y =\frac2{12}$

20. JenniferSmart1 Group Title

was this the original equation? $\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}$ or this $\frac{4}{12y}+\frac{3}{12}=\frac{5}{12}$ ?

21. rawrrainbowsz2 Group Title

the 1st one

22. JenniferSmart1 Group Title

sorry i've been mistyping let's try that again LOL

23. JenniferSmart1 Group Title

$\frac{4}{12}y=\frac{2}{12}$ now we can multiply both sides by $\frac{12}1$ to get rid of the 12 in the denominator because we don't need it anymore. It makes it easier to solve for y this way so $\frac{12}1 \cdot \frac{4}{12}y=\frac{12}1 \cdot \frac{2}{12}$

24. rawrrainbowsz2 Group Title

is it 2 ? :D

25. JenniferSmart1 Group Title

almost so we're left with 4y=2 so what does y=?

26. rawrrainbowsz2 Group Title

2 .....

27. JenniferSmart1 Group Title

$y=\frac24$

28. rawrrainbowsz2 Group Title

:( i was close

29. JenniferSmart1 Group Title

because we have to divide by 4 to get y by itself

30. JenniferSmart1 Group Title

Yep you were almost there! so now you just need to simplify $\frac24$

31. rawrrainbowsz2 Group Title

ohhh ok lol

32. rawrrainbowsz2 Group Title

1/2

33. JenniferSmart1 Group Title

$y=\frac12$ very good!
