NC=42
Swap sides so that all variable terms are on the left hand side.
\frac{NC}{N}=\frac{42}{N}
Divide both sides by N.
C=\frac{42}{N}
Dividing by N undoes the multiplication by N.
NC=42
Swap sides so that all variable terms are on the left hand side.
CN=42
The equation is in standard form.
\frac{CN}{C}=\frac{42}{C}
Divide both sides by C.
N=\frac{42}{C}
Dividing by C undoes the multiplication by C.
