x_{3}yx=90
The equation is in standard form.
\frac{x_{3}yx}{x_{3}y}=\frac{90}{x_{3}y}
Divide both sides by x_{3}y.
x=\frac{90}{x_{3}y}
Dividing by x_{3}y undoes the multiplication by x_{3}y.
xyx_{3}=90
The equation is in standard form.
\frac{xyx_{3}}{xy}=\frac{90}{xy}
Divide both sides by xy.
x_{3}=\frac{90}{xy}
Dividing by xy undoes the multiplication by xy.
