How do you solve P = C+MC, for M?

Answer :

you just need to leave M alone

[tex]\begin{gathered} P=C+MC \\ \end{gathered}[/tex]

so , the first C is adding so, change side to subtract

[tex]P-C=MC[/tex]

and the second C is multiplying then goes to the other side to divide

[tex]\frac{P-C}{C}=M[/tex]
