Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$-\frac{1}{8}x^{2}E=y$$

Mae'r hafaliad yn y ffurf safonol.

$$\left(-\frac{x^{2}}{8}\right)E=y$$

Rhannu’r ddwy ochr â -\frac{1}{8}x^{2}.

$$\frac{\left(-\frac{x^{2}}{8}\right)E}{-\frac{x^{2}}{8}}=\frac{y}{-\frac{x^{2}}{8}}$$

Mae rhannu â -\frac{1}{8}x^{2} yn dad-wneud lluosi â -\frac{1}{8}x^{2}.

$$E=\frac{y}{-\frac{x^{2}}{8}}$$

Rhannwch y â -\frac{1}{8}x^{2}.

$$E=-\frac{8y}{x^{2}}$$

Datrys ar gyfer E

$$\left\{\begin{matrix}E=-\frac{8y}{x^{2}}\text{, }&x\neq 0\\E\in \mathrm{R}\text{, }&y=0\text{ and }x=0\end{matrix}\right.$$
