5x=\Delta y
Swap sides so that all variable terms are on the left hand side.
5x=y\Delta
The equation is in standard form.
\frac{5x}{5}=\frac{y\Delta }{5}
Divide both sides by 5.
x=\frac{y\Delta }{5}
Dividing by 5 undoes the multiplication by 5.
\Delta y=5x
The equation is in standard form.
\frac{\Delta y}{\Delta }=\frac{5x}{\Delta }
Divide both sides by \Delta .
y=\frac{5x}{\Delta }
Dividing by \Delta undoes the multiplication by \Delta .
