minus

OpenStudy (anonymous):

OpenStudy (anonymous):

Is it 5/y^2 - 4/3y

OpenStudy (anonymous):

\[\frac{ 15-4y }{ 3y ^{2} }\]

OpenStudy (anonymous):

yes @ritez

OpenStudy (anonymous):

how'd you find that out? @Kwarkark

OpenStudy (anonymous):

Make the numerators so that they are equal. This will make it possible to subtract or add another fraction to it.

OpenStudy (anonymous):

easy enough

OpenStudy (anonymous):

so: \[\frac{ 5 }{ y ^{2} } = \frac{ 15 }{ 3y ^{2} } \] and \[\frac{ 4 }{ 3y } = \frac{ 4y }{ 3y ^{2} }\]

OpenStudy (anonymous):

alright how did you get an exponent of two in the second part?

OpenStudy (anonymous):

I multiplied both sides by y. And y*y = y^2

OpenStudy (anonymous):

perfect. okay thanks!!!!
