z=\frac{1}{12}x-7.275
Divide each term of x-87.3 by 12 to get \frac{1}{12}x-7.275.
\frac{1}{12}x-7.275=z
Swap sides so that all variable terms are on the left hand side.
\frac{1}{12}x=z+7.275
Add 7.275 to both sides.
\frac{\frac{1}{12}x}{\frac{1}{12}}=\frac{z+7.275}{\frac{1}{12}}
Multiply both sides by 12.
x=\frac{z+7.275}{\frac{1}{12}}
Dividing by \frac{1}{12} undoes the multiplication by \frac{1}{12}.
x=12z+87.3
Divide z+7.275 by \frac{1}{12} by multiplying z+7.275 by the reciprocal of \frac{1}{12}.
z=\frac{1}{12}x-7.275
Divide each term of x-87.3 by 12 to get \frac{1}{12}x-7.275.
