Find b: 5a/c - y - d/b =z

 

\(\color{red}\frac{5a}{c}-y-\frac{d}{b}=z\\-\frac{d}{b}=z+y-\frac{5a}{c}\\-\frac{d}{b}=\frac{cz+cy-5a}{c}\)

\(-\frac{b}{d}=\frac{c}{cz+cy-5a}\\\color {blue}b=\frac{cd}{5a-cz-cy}\)

 

Find m: 4n/ab - c/m=x

 

\(\color{red}\frac{4n}{ab}-\frac{c}{m}=x\\-\frac{c}{m}=x-\frac{4n}{ab}\\ -\frac{c}{m}=\frac{abx-4n}{ab}\\ -\frac{m}{c}=\frac{ab}{abx-4n}\)

\(m=\frac{abc}{4n-abx}\)
