Question

Solve the following equation for bn + 3Gb = qb

Answer 1

To determine an equation and make b the subject:

`n+3Gb=qb`
`\begin{gathered} n+3Gb=qb \\ \text{make b the subject of the formula} \\ 3Gb-qb=-n \\ b(3G-q)=-n \\ \text{divide both side by 3G-q} \end{gathered}`
`\begin{gathered} b(3G-q)=-n \\ (b(3G-q))/(3G-q)=-(n)/(3G-q) \\ b=(-n)/(3G-q) \end{gathered}`

Hence the value of b in the above expresion is

`b=(-n)/(3G-q)`
