Rhannu
Copïo i clipfwrdd
1.3=0.03+\frac{35}{13}x
Rhannu 0.7x â 0.26 i gael \frac{35}{13}x.
0.03+\frac{35}{13}x=1.3
Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.
\frac{35}{13}x=1.3-0.03
Tynnu 0.03 o'r ddwy ochr.
\frac{35}{13}x=1.27
Tynnu 0.03 o 1.3 i gael 1.27.
x=\frac{1.27}{\frac{35}{13}}
Rhannu’r ddwy ochr â \frac{35}{13}.
