Whakaoti i te x2+8-y=y

$$x2+8-y=y$$

Whakaoti mō x_2

$$x_{2}=2\left(y-4\right)$$

Ngā Upane Otinga

Tangohia te 8 mai i ngā taha e rua.

$$x_{2}-y=y-8$$

Me tāpiri te y ki ngā taha e rua.

$$x_{2}=y-8+y$$

Pahekotia te y me y, ka 2y.

$$x_{2}=2y-8$$

Whakaoti mō y

$$y=\frac{x_{2}+8}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te y mai i ngā taha e rua.

$$x_{2}+8-y-y=0$$

Pahekotia te -y me -y, ka -2y.

$$x_{2}+8-2y=0$$

Tangohia te x_{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$8-2y=-x_{2}$$

Tangohia te 8 mai i ngā taha e rua.

$$-2y=-x_{2}-8$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2y}{-2}=\frac{-x_{2}-8}{-2}$$

Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.

$$y=\frac{-x_{2}-8}{-2}$$

Whakawehe -x_{2}-8 ki te -2.

$$y=\frac{x_{2}}{2}+4$$
