Best ResponseYou've already chosen the best response.0you 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

Best ResponseYou've already chosen the best response.0almost So it's \[\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}\] because \[\frac44\cdot \frac{1}{3}y+\frac33 \cdot \frac{1}{4}=\frac{5}{12}\]

Best ResponseYou've already chosen the best response.0does that make sense?

Best ResponseYou've already chosen the best response.0so 5/12 stays the same ?

Best ResponseYou've already chosen the best response.0yes 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

Best ResponseYou've already chosen the best response.0\[\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}\] 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 \[\frac{4}{12}y+\cancel{\frac{3}{12}\frac3{12}}=\frac{5}{12}\frac3{12}\]

Best ResponseYou've already chosen the best response.0now we need to get the y out of the denominator. do you know how to do that?

Best ResponseYou've already chosen the best response.0wait, is y in the denominator or is it just like this: \[\frac4{12}y =\frac2{12}\]

Best ResponseYou've already chosen the best response.0was this the original equation? \[\frac{4}{12}y+\frac{3}{12}=\frac{5}{12}\] or this \[\frac{4}{12y}+\frac{3}{12}=\frac{5}{12}\] ?

Best ResponseYou've already chosen the best response.0sorry i've been mistyping let's try that again LOL

Best ResponseYou've already chosen the best response.0\[\frac{4}{12}y=\frac{2}{12}\] 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 \[\frac{12}1 \cdot \frac{4}{12}y=\frac{12}1 \cdot \frac{2}{12}\]

Best ResponseYou've already chosen the best response.0almost so we're left with 4y=2 so what does y=?

anonymous

Best ResponseYou've already chosen the best response.0because we have to divide by 4 to get y by itself

Best ResponseYou've already chosen the best response.0Yep you were almost there! so now you just need to simplify \[\frac24\]

Best ResponseYou've already chosen the best response.0\[y=\frac12\] very good!
