Question

a/b(2x - 12) = c/d

Answer 1

solve for x?
\[\frac{a}{b}(2x-12)=\frac{c}{d}\]
multiply by the reciprocal
\[2x-12=\frac{c}{d}\times \frac{b}{a}=\frac{bc}{ad}\]
divide by 2
\[x-6=\frac{bc}{2ad}\]
add 6
\[x=\frac{bc}{2ad}+6\]

Answer 2

ad=(2bcx-12bc) ==> 2bcx=ad+12bc ==> x= (ad+12bc)/2bc

Answer 3

= ad/2bc +6
