Defnyddio’r briodwedd ddosbarthu i luosi \frac{1}{2} â 4x-8.

$$\frac{1}{2}\times 4x+\frac{1}{2}\left(-8\right)+3x=36$$

Lluosi \frac{1}{2} a 4 i gael \frac{4}{2}.

$$\frac{4}{2}x+\frac{1}{2}\left(-8\right)+3x=36$$

Rhannu 4 â 2 i gael 2.

$$2x+\frac{1}{2}\left(-8\right)+3x=36$$

Lluosi \frac{1}{2} a -8 i gael \frac{-8}{2}.

$$2x+\frac{-8}{2}+3x=36$$

Rhannu -8 â 2 i gael -4.

$$2x-4+3x=36$$

Cyfuno 2x a 3x i gael 5x.

$$5x-4=36$$

Ychwanegu 4 at y ddwy ochr.

$$5x=36+4$$

Adio 36 a 4 i gael 40.

$$5x=40$$

Rhannu’r ddwy ochr â 5.

$$x=\frac{40}{5}$$

Rhannu 40 â 5 i gael 8.

$$x=8$$
