Datrys y=3xdx

$$y = 3 x d x$$

Datrys ar gyfer d (complex solution)

$$\left\{\begin{matrix}d=\frac{y}{3x^{2}}\text{, }&x\neq 0\\d\in \mathrm{C}\text{, }&y=0\text{ and }x=0\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliad Llinol

Lluosi x a x i gael x^{2}.

$$y=3x^{2}d$$

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

$$3x^{2}d=y$$

Rhannu’r ddwy ochr â 3x^{2}.

$$\frac{3x^{2}d}{3x^{2}}=\frac{y}{3x^{2}}$$

Mae rhannu â 3x^{2} yn dad-wneud lluosi â 3x^{2}.

$$d=\frac{y}{3x^{2}}$$

Datrys ar gyfer d

$$\left\{\begin{matrix}d=\frac{y}{3x^{2}}\text{, }&x\neq 0\\d\in \mathrm{R}\text{, }&y=0\text{ and }x=0\end{matrix}\right.$$
