Camau ar gyfer Datrys Hafaliad Llinol

Rhannu’r ddwy ochr â 667.

$$\frac{1}{667}=\frac{x\times 10^{-11}\times 2\times 2}{D^{2}}$$

Lluoswch ddwy ochr yr hafaliad wrth 667D^{2}, lluoswm cyffredin lleiaf 667,D^{2}.

$$D^{2}=667x\times 10^{-11}\times 2\times 2$$

Cyfrifo 10 i bŵer -11 a chael \frac{1}{100000000000}.

$$D^{2}=667x\times \frac{1}{100000000000}\times 2\times 2$$

Lluosi 667 a \frac{1}{100000000000} i gael \frac{667}{100000000000}.

$$D^{2}=\frac{667}{100000000000}x\times 2\times 2$$

Lluosi \frac{667}{100000000000} a 2 i gael \frac{667}{50000000000}.

$$D^{2}=\frac{667}{50000000000}x\times 2$$

Lluosi \frac{667}{50000000000} a 2 i gael \frac{667}{25000000000}.

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

$$\frac{667}{25000000000}x=D^{2}$$

Rhannu dwy ochr hafaliad â \frac{667}{25000000000}, sydd yr un peth â lluosi’r ddwy ochr â chilydd y ffracsiwn.

$$\frac{\frac{667}{25000000000}x}{\frac{667}{25000000000}}=\frac{D^{2}}{\frac{667}{25000000000}}$$

Mae rhannu â \frac{667}{25000000000} yn dad-wneud lluosi â \frac{667}{25000000000}.

$$x=\frac{D^{2}}{\frac{667}{25000000000}}$$

Rhannwch D^{2} â \frac{667}{25000000000} drwy luosi D^{2} â chilydd \frac{667}{25000000000}.

$$x=\frac{25000000000D^{2}}{667}$$
