\frac{1}{2}x+20=y

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

\frac{1}{2}x=y-20

Tynnu 20 o'r ddwy ochr.

\frac{\frac{1}{2}x}{\frac{1}{2}}=\frac{y-20}{\frac{1}{2}}

Lluosi’r ddwy ochr â 2.

x=\frac{y-20}{\frac{1}{2}}

Mae rhannu â \frac{1}{2} yn dad-wneud lluosi â \frac{1}{2}.

x=2y-40

Rhannwch y-20 â \frac{1}{2} drwy luosi y-20 â chilydd \frac{1}{2}.
