Question

Solve for N: X= MN - P

Answer 1

The given equation is

`X=MN-P`

First, we add P on each side.

`\begin{gathered} X+P=MN-P+P \\ X+P=MN \end{gathered}`

Then, we divide the equation by M.

`\begin{gathered} (X+P)/(M)=(MN)/(M) \\ N=(X+P)/(M) \end{gathered}`

Therefore, the solution is

`N=(X+P)/(M)`
