Whakaoti i te x.2+8-y=y

$$x.2+8-y=y$$

Whakaoti mō x

$$x=10\left(y-4\right)$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 8 mai i ngā taha e rua.

$$x\times 0.2-y=y-8$$

Me tāpiri te y ki ngā taha e rua.

$$x\times 0.2=y-8+y$$

Pahekotia te y me y, ka 2y.

$$x\times 0.2=2y-8$$

He hanga arowhānui tō te whārite.

$$0.2x=2y-8$$

Me whakarea ngā taha e rua ki te 5.

$$\frac{0.2x}{0.2}=\frac{2y-8}{0.2}$$

Mā te whakawehe ki te 0.2 ka wetekia te whakareanga ki te 0.2.

$$x=\frac{2y-8}{0.2}$$

Whakawehe -8+2y ki te 0.2 mā te whakarea -8+2y ki te tau huripoki o 0.2.

$$x=10y-40$$

Whakaoti mō y

$$y=\frac{x+40}{10}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te y mai i ngā taha e rua.

$$x\times 0.2+8-y-y=0$$

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

$$x\times 0.2+8-2y=0$$

Tangohia te x\times 0.2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$8-2y=-x\times 0.2$$

Tangohia te 8 mai i ngā taha e rua.

$$-2y=-x\times 0.2-8$$

Whakareatia te -1 ki te 0.2, ka -0.2.

$$-2y=-0.2x-8$$

He hanga arowhānui tō te whārite.

$$-2y=-\frac{x}{5}-8$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2y}{-2}=\frac{-\frac{x}{5}-8}{-2}$$

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

$$y=\frac{-\frac{x}{5}-8}{-2}$$

Whakawehe -\frac{x}{5}-8 ki te -2.

$$y=\frac{x}{10}+4$$
