Whakaoti i te 2x1+12x2+22x3=4

$$2x1+12x2+22x3=4$$

Whakaoti mō x_1

$$x_{1}=2-11x_{3}-6x_{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 12x_{2} mai i ngā taha e rua.

$$2x_{1}+22x_{3}=4-12x_{2}$$

Tangohia te 22x_{3} mai i ngā taha e rua.

$$2x_{1}=4-12x_{2}-22x_{3}$$

He hanga arowhānui tō te whārite.

$$2x_{1}=4-22x_{3}-12x_{2}$$

Whakawehea ngā taha e rua ki te 2.

$$\frac{2x_{1}}{2}=\frac{4-22x_{3}-12x_{2}}{2}$$

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

$$x_{1}=\frac{4-22x_{3}-12x_{2}}{2}$$

Whakawehe 4-12x_{2}-22x_{3} ki te 2.

$$x_{1}=2-11x_{3}-6x_{2}$$

Whakaoti mō x_2

$$x_{2}=-\frac{x_{1}}{6}-\frac{11x_{3}}{6}+\frac{1}{3}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2x_{1} mai i ngā taha e rua.

$$12x_{2}+22x_{3}=4-2x_{1}$$

Tangohia te 22x_{3} mai i ngā taha e rua.

$$12x_{2}=4-2x_{1}-22x_{3}$$

He hanga arowhānui tō te whārite.

$$12x_{2}=4-22x_{3}-2x_{1}$$

Whakawehea ngā taha e rua ki te 12.

$$\frac{12x_{2}}{12}=\frac{4-22x_{3}-2x_{1}}{12}$$

Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.

$$x_{2}=\frac{4-22x_{3}-2x_{1}}{12}$$

Whakawehe 4-2x_{1}-22x_{3} ki te 12.

$$x_{2}=-\frac{x_{1}}{6}-\frac{11x_{3}}{6}+\frac{1}{3}$$
