$$\left. \begin{array} { l } { \text { Solve the linear equation. } } \\ { \qquad \frac { 3 x } { 2 } + \frac { 1 } { 2 } + 3 = \frac { 8 x } { 5 } - \frac { 6 } { 5 } } \end{array} \right.$$

Datrys ar gyfer x

$$x = \frac{67}{16} = 4\frac{3}{16} = 4.1875$$

Camau ar gyfer Datrys Hafaliad Llinol

Lluoswch ddwy ochr yr hafaliad wrth 10, lluoswm cyffredin lleiaf 2,5.

$$20+5+30=2\times 8x-12$$

Adio 20 a 5 i gael 25.

$$25+30=2\times 8x-12$$

Adio 25 a 30 i gael 55.

$$55=2\times 8x-12$$

Lluosi 2 a 8 i gael 16.

$$55=16x-12$$

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$16x-12=55$$

Ychwanegu 12 at y ddwy ochr.

$$16x=55+12$$

Adio 55 a 12 i gael 67.

$$16x=67$$

Rhannu’r ddwy ochr â 16.

$$x=\frac{67}{16}$$
