Datrys 14/sqrt{5}=x/7

$$\frac { 14 } { \sqrt { 5 } } = \frac { x } { 7 }$$

Datrys ar gyfer x

$$x = \frac{98 \sqrt{5}}{5} \approx 43.826932359$$

Camau ar gyfer Datrys Hafaliad Llinol

Lluoswch ddwy ochr yr hafaliad â 7.

$$\frac{7}{5}\times 5^{\frac{1}{2}}\times 14=x$$

Mynegwch \frac{7}{5}\times 14 fel ffracsiwn unigol.

$$\frac{7\times 14}{5}\times 5^{\frac{1}{2}}=x$$

Lluosi 7 a 14 i gael 98.

$$\frac{98}{5}\times 5^{\frac{1}{2}}=x$$

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

$$x=\frac{98}{5}\times 5^{\frac{1}{2}}$$

Aildrefnu'r termau.

$$x=\frac{98}{5}\sqrt{5}$$
