Datrys ar gyfer x

$$x=\frac{2\left(y+2k\right)}{3}$$

Camau ar gyfer Datrys Hafaliad Llinol

Ychwanegu 2y at y ddwy ochr.

$$3x=4k+2y$$

Mae'r hafaliad yn y ffurf safonol.

$$3x=2y+4k$$

Rhannu’r ddwy ochr â 3.

$$\frac{3x}{3}=\frac{2y+4k}{3}$$

Mae rhannu â 3 yn dad-wneud lluosi â 3.

$$x=\frac{2y+4k}{3}$$
