yx=30-18
Subtract 18 from both sides.
yx=12
Subtract 18 from 30 to get 12.
\frac{yx}{y}=\frac{12}{y}
Divide both sides by y.
x=\frac{12}{y}
Dividing by y undoes the multiplication by y.
yx=30-18
Subtract 18 from both sides.
yx=12
Subtract 18 from 30 to get 12.
xy=12
The equation is in standard form.
\frac{xy}{x}=\frac{12}{x}
Divide both sides by x.
y=\frac{12}{x}
Dividing by x undoes the multiplication by x.
