800x+15200=y
Swap sides so that all variable terms are on the left hand side.
800x=y-15200
Subtract 15200 from both sides.
\frac{800x}{800}=\frac{y-15200}{800}
Divide both sides by 800.
x=\frac{y-15200}{800}
Dividing by 800 undoes the multiplication by 800.
x=\frac{y}{800}-19
Divide y-15200 by 800.
