AS=33000-BY
Subtract BY from both sides.
SA=33000-BY
The equation is in standard form.
\frac{SA}{S}=\frac{33000-BY}{S}
Divide both sides by S.
A=\frac{33000-BY}{S}
Dividing by S undoes the multiplication by S.
BY=33000-AS
Subtract AS from both sides.
YB=33000-AS
The equation is in standard form.
\frac{YB}{Y}=\frac{33000-AS}{Y}
Divide both sides by Y.
B=\frac{33000-AS}{Y}
Dividing by Y undoes the multiplication by Y.
