Camau Ateb

Ystyriwch yr hafaliad cyntaf. Tynnu 11.778 o'r ddwy ochr.

$$0.53x=0.86-11.778$$

Tynnu 11.778 o 0.86 i gael -10.918.

$$0.53x=-10.918$$

Rhannu’r ddwy ochr â 0.53.

$$x=\frac{-10.918}{0.53}$$

Ehangu \frac{-10.918}{0.53} drwy luosi'r rhifiadur a'r enwadur gyda 1000.

$$x=\frac{-10918}{530}$$

Lleihau'r ffracsiwn \frac{-10918}{530} i'r graddau lleiaf posib drwy dynnu a chanslo allan 106.

$$x=-\frac{103}{5}$$

Mae’r system wedi’i datrys nawr.

$$x=-\frac{103}{5} y=0.468 z=0.468 a=0.468 b=0.468 c=0.468 d=0.468$$
