Whakaoti i te m_{3}-0.28N_{2}=100

$$m _ { 3 } - 0.28 N _ { 2 } = 100$$

Whakaoti mō N_2

$$N_{2}=\frac{25m_{3}-2500}{7}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$-0.28N_{2}=100-m_{3}$$

Whakawehea ngā taha e rua o te whārite ki te -0.28, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-0.28N_{2}}{-0.28}=\frac{100-m_{3}}{-0.28}$$

Mā te whakawehe ki te -0.28 ka wetekia te whakareanga ki te -0.28.

$$N_{2}=\frac{100-m_{3}}{-0.28}$$

Whakawehe 100-m_{3} ki te -0.28 mā te whakarea 100-m_{3} ki te tau huripoki o -0.28.

$$N_{2}=\frac{25m_{3}-2500}{7}$$

Whakaoti mō m_3

$$m_{3}=\frac{7N_{2}}{25}+100$$

Ngā Upane Otinga

Me tāpiri te 0.28N_{2} ki ngā taha e rua.

$$m_{3}=100+0.28N_{2}$$
