Whakaoti i te -16/5+4y=14

$$- \frac{ 16 }{ 5 } +4y = 14$$

Whakaoti mō y

$$y = \frac{43}{10} = 4\frac{3}{10} = 4.3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te \frac{16}{5} ki ngā taha e rua.

$$4y=14+\frac{16}{5}$$

Me tahuri te 14 ki te hautau \frac{70}{5}.

$$4y=\frac{70}{5}+\frac{16}{5}$$

Tā te mea he rite te tauraro o \frac{70}{5} me \frac{16}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$4y=\frac{70+16}{5}$$

Tāpirihia te 70 ki te 16, ka 86.

$$4y=\frac{86}{5}$$

Whakawehea ngā taha e rua ki te 4.

$$y=\frac{\frac{86}{5}}{4}$$

Tuhia te \frac{\frac{86}{5}}{4} hei hautanga kotahi.

$$y=\frac{86}{5\times 4}$$

Whakareatia te 5 ki te 4, ka 20.

$$y=\frac{86}{20}$$

Whakahekea te hautanga \frac{86}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$y=\frac{43}{10}$$
