\[\frac 2y + \frac 52 = 4 - \frac 2{3y}\]
???
OpenStudy (anonymous):
i multiplied everything by 6y
OpenStudy (lgbasallote):
is that the question?
OpenStudy (anonymous):
just solve for y..."solve each equation" is what the book says
OpenStudy (lgbasallote):
but did i write your question right?

yes
OpenStudy (lgbasallote):
if you multiply everything by 6y you should get
\[\implies 12 + 15y = 24y -4\]
right?
OpenStudy (anonymous):
yes
OpenStudy (lgbasallote):
so iff you add 4 to both sides and subtract 15y to both sides...you should get..
\[\implies 16 = 9y\]
right?
OpenStudy (anonymous):
wait i got something different

after multiplying everything by 6y i got
12+15y=24y-4y
OpenStudy (lgbasallote):
6y/3y = 2...then 2 x 2 = 4
there should be no y
OpenStudy (lgbasallote):
you made a mistake
OpenStudy (anonymous):
okay walk me through this
OpenStudy (lgbasallote):
what dont you get?

OpenStudy (lgbasallote):
\[\huge \frac{2}{3y} \times 6y \implies \frac{2}{\cancel{3y}} \times \cancel{6y}^2 \implies 2\times 2 \implies 4\]
OpenStudy (lgbasallote):
that's the only mistake you did
