Whakaoti i te x6-900+x1.5=1200

$$x6-900+x1.5 = 1200$$

Whakaoti mō x_1

$$x_{1}=4200-2x_{6}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x_{6} mai i ngā taha e rua.

$$-900+x_{1}\times 0.5=1200-x_{6}$$

Me tāpiri te 900 ki ngā taha e rua.

$$x_{1}\times 0.5=1200-x_{6}+900$$

Tāpirihia te 1200 ki te 900, ka 2100.

$$x_{1}\times 0.5=2100-x_{6}$$

He hanga arowhānui tō te whārite.

$$0.5x_{1}=2100-x_{6}$$

Me whakarea ngā taha e rua ki te 2.

$$\frac{0.5x_{1}}{0.5}=\frac{2100-x_{6}}{0.5}$$

Mā te whakawehe ki te 0.5 ka wetekia te whakareanga ki te 0.5.

$$x_{1}=\frac{2100-x_{6}}{0.5}$$

Whakawehe 2100-x_{6} ki te 0.5 mā te whakarea 2100-x_{6} ki te tau huripoki o 0.5.

$$x_{1}=4200-2x_{6}$$

Whakaoti mō x_6

$$x_{6}=-\frac{x_{1}}{2}+2100$$

Ngā Upane Otinga

Me tāpiri te 900 ki ngā taha e rua.

$$x_{6}+x_{1}\times 0.5=1200+900$$

Tāpirihia te 1200 ki te 900, ka 2100.

$$x_{6}+x_{1}\times 0.5=2100$$

Tangohia te x_{1}\times 0.5 mai i ngā taha e rua.

$$x_{6}=2100-x_{1}\times 0.5$$

Whakareatia te -1 ki te 0.5, ka -0.5.

$$x_{6}=2100-0.5x_{1}$$
