we are given

\frac{a}{b} (2x-12)=\frac{c}{d}

we can solve for x

We can isolate x

step-1: Multiply both sides by b/a

\frac{b}{a}*\frac{a}{b} (2x-12)=\frac{b}{a}*\frac{c}{d}

(2x-12)=\frac{bc}{ad}

step-2:Add 12 both sides

(2x-12)+12=\frac{bc}{ad}+12

2x=\frac{bc}{ad}+12

step-3: combine right side

2x=\frac{bc+12ad}{ad}

step-4:Divide both sides by 2

x=\frac{bc+12ad}{2ad}..............Answer
