Camau ar gyfer Datrys Hafaliad Llinol

Tynnu \frac{4}{5}x o'r ddwy ochr.

$$13x-36-\frac{4}{5}x=2$$

Cyfuno 13x a -\frac{4}{5}x i gael \frac{61}{5}x.

$$\frac{61}{5}x-36=2$$

Ychwanegu 36 at y ddwy ochr.

$$\frac{61}{5}x=2+36$$

Adio 2 a 36 i gael 38.

$$\frac{61}{5}x=38$$

Lluoswch y ddwy ochr â \frac{5}{61}, cilyddol \frac{61}{5}.

$$x=38\times \frac{5}{61}$$

Mynegwch 38\times \frac{5}{61} fel ffracsiwn unigol.

$$x=\frac{38\times 5}{61}$$

Lluosi 38 a 5 i gael 190.

$$x=\frac{190}{61}$$
