Rhannu
Copïo i clipfwrdd
\sqrt{\frac{1}{5}x-\frac{1}{2}}=10
Rhannu pob term 2x-5 â 10 i gael \frac{1}{5}x-\frac{1}{2}.
\frac{1}{5}x-\frac{1}{2}=100
Sgwariwch ddwy ochr yr hafaliad.
\frac{1}{5}x-\frac{1}{2}-\left(-\frac{1}{2}\right)=100-\left(-\frac{1}{2}\right)
Adio \frac{1}{2} at ddwy ochr yr hafaliad.
\frac{1}{5}x=100-\left(-\frac{1}{2}\right)
Mae tynnu -\frac{1}{2} o’i hun yn gadael 0.
\frac{1}{5}x=\frac{201}{2}
Tynnu -\frac{1}{2} o 100.
\frac{\frac{1}{5}x}{\frac{1}{5}}=\frac{\frac{201}{2}}{\frac{1}{5}}
Lluosi’r ddwy ochr â 5.
x=\frac{\frac{201}{2}}{\frac{1}{5}}
Mae rhannu â \frac{1}{5} yn dad-wneud lluosi â \frac{1}{5}.
x=\frac{1005}{2}
Rhannwch \frac{201}{2} â \frac{1}{5} drwy luosi \frac{201}{2} â chilydd \frac{1}{5}.
