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

    we add 12 to both sides for the first equation

    \[\frac{ 3 }{ 4 y}-12+12 = 12+12\] simplifed to \[\frac{ 3 }{ 4 }y =24\]

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

    \[\frac{ 3 }{ 4 } (x-12)=12\] multiply 4 on both sides we get \[3(x-12) = 48\]
