Answer:
[tex]x=p(m-n)[/tex]
Step-by-step explanation:
[tex]m=n+\frac{x}{p}[/tex]
Put n to the other side by subtraction.
[tex]m(-n)=n(-n)+\frac{x}{p}\\m-n=+\frac{x}{p}\\[/tex]
Use multiplication with 'p' to isolate x.
[tex](p)(m-n)=\frac{x}{p}(p)\\ p(m-n)=x[/tex]
x is now isolated.
[tex]x=p(m-n)[/tex]
