Camau Ateb

Ystyriwch yr hafaliad cyntaf. Cyfuno 24x a -10x i gael 14x.

$$14x+8+14=12-2x+8x+34$$

Adio 8 a 14 i gael 22.

$$14x+22=12-2x+8x+34$$

Cyfuno -2x a 8x i gael 6x.

$$14x+22=12+6x+34$$

Adio 12 a 34 i gael 46.

$$14x+22=46+6x$$

Tynnu 6x o'r ddwy ochr.

$$14x+22-6x=46$$

Cyfuno 14x a -6x i gael 8x.

$$8x+22=46$$

Tynnu 22 o'r ddwy ochr.

$$8x=46-22$$

Tynnu 22 o 46 i gael 24.

$$8x=24$$

Rhannu’r ddwy ochr â 8.

$$x=\frac{24}{8}$$

Rhannu 24 â 8 i gael 3.

$$x=3$$
