-\frac{1}{8}x^{2}E=y
Swap sides so that all variable terms are on the left hand side.
\left(-\frac{x^{2}}{8}\right)E=y
The equation is in standard form.
\frac{\left(-\frac{x^{2}}{8}\right)E}{-\frac{x^{2}}{8}}=\frac{y}{-\frac{x^{2}}{8}}
Divide both sides by -\frac{1}{8}x^{2}.
E=\frac{y}{-\frac{x^{2}}{8}}
Dividing by -\frac{1}{8}x^{2} undoes the multiplication by -\frac{1}{8}x^{2}.
E=-\frac{8y}{x^{2}}
Divide y by -\frac{1}{8}x^{2}.
