Rhannu
Copïo i clipfwrdd
y=x+72-\frac{31}{8}xy+4z
Rhannu 93x â 24 i gael \frac{31}{8}x.
x+72-\frac{31}{8}xy+4z=y
Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.
x-\frac{31}{8}xy+4z=y-72
Tynnu 72 o'r ddwy ochr.
x-\frac{31}{8}xy=y-72-4z
Tynnu 4z o'r ddwy ochr.
\left(1-\frac{31}{8}y\right)x=y-72-4z
Cyfuno pob term sy'n cynnwys x.
\left(-\frac{31y}{8}+1\right)x=y-4z-72
Mae'r hafaliad yn y ffurf safonol.
\frac{\left(-\frac{31y}{8}+1\right)x}{-\frac{31y}{8}+1}=\frac{y-4z-72}{-\frac{31y}{8}+1}
Rhannu’r ddwy ochr â 1-\frac{31}{8}y.
x=\frac{y-4z-72}{-\frac{31y}{8}+1}
Mae rhannu â 1-\frac{31}{8}y yn dad-wneud lluosi â 1-\frac{31}{8}y.
x=\frac{8\left(y-4z-72\right)}{8-31y}
Rhannwch y-72-4z â 1-\frac{31}{8}y.
y=x+72-\frac{31}{8}xy+4z
Rhannu 93x â 24 i gael \frac{31}{8}x.
y+\frac{31}{8}xy=x+72+4z
Ychwanegu \frac{31}{8}xy at y ddwy ochr.
\left(1+\frac{31}{8}x\right)y=x+72+4z
Cyfuno pob term sy'n cynnwys y.
\left(\frac{31x}{8}+1\right)y=x+4z+72
Mae'r hafaliad yn y ffurf safonol.
\frac{\left(\frac{31x}{8}+1\right)y}{\frac{31x}{8}+1}=\frac{x+4z+72}{\frac{31x}{8}+1}
Rhannu’r ddwy ochr â 1+\frac{31}{8}x.
y=\frac{x+4z+72}{\frac{31x}{8}+1}
Mae rhannu â 1+\frac{31}{8}x yn dad-wneud lluosi â 1+\frac{31}{8}x.
y=\frac{8\left(x+4z+72\right)}{31x+8}
Rhannwch x+72+4z â 1+\frac{31}{8}x.
