    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

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

    so 5/12 stays the same ?

    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

    \[\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}\] 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 \[\frac{4}{12}y+\cancel{\frac{3}{12}-\frac3{12}}=\frac{5}{12}-\frac3{12}\]

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

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

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

    \[\frac{4}{12}y=\frac{2}{12}\] 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 \[\frac{12}1 \cdot \frac{4}{12}y=\frac{12}1 \cdot \frac{2}{12}\]

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

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

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