i dont know how to solve it

\[\frac{ 3 }{ 4 }y-12=12\] and\[\frac{ 3 }{ 4 }(x-12)=12\]

how do i solve it

OpenStudy (anonymous):
we add 12 to both sides for the first equation

OpenStudy (anonymous):
\[\frac{ 3 }{ 4 y}-12+12 = 12+12\] simplifed to \[\frac{ 3 }{ 4 }y =24\]

multiply both sides by 4 to cancel the denominator we get 3y=96
