Whakaoti mō x
x=\frac{20y-x_{6}z}{3}
Whakaoti mō x_6
\left\{\begin{matrix}x_{6}=-\frac{3x-20y}{z}\text{, }&z\neq 0\\x_{6}\in \mathrm{R}\text{, }&x=\frac{20y}{3}\text{ and }z=0\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
3x=20y-zx_{6}
Tangohia te zx_{6} mai i ngā taha e rua.
3x=20y-x_{6}z
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{20y-x_{6}z}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{20y-x_{6}z}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
zx_{6}=20y-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{zx_{6}}{z}=\frac{20y-3x}{z}
Whakawehea ngā taha e rua ki te z.
x_{6}=\frac{20y-3x}{z}
Mā te whakawehe ki te z ka wetekia te whakareanga ki te z.
