Whakaoti i te 5(3x-2)=26

$$5 ( 3 x - 2 ) = 26$$

Whakaoti mō x

$$x = \frac{12}{5} = 2\frac{2}{5} = 2.4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 5.

$$3x-2=\frac{26}{5}$$

Me tāpiri te 2 ki ngā taha e rua.

$$3x=\frac{26}{5}+2$$

Me tahuri te 2 ki te hautau \frac{10}{5}.

$$3x=\frac{26}{5}+\frac{10}{5}$$

Tā te mea he rite te tauraro o \frac{26}{5} me \frac{10}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$3x=\frac{26+10}{5}$$

Tāpirihia te 26 ki te 10, ka 36.

$$3x=\frac{36}{5}$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{\frac{36}{5}}{3}$$

Tuhia te \frac{\frac{36}{5}}{3} hei hautanga kotahi.

$$x=\frac{36}{5\times 3}$$

Whakareatia te 5 ki te 3, ka 15.

$$x=\frac{36}{15}$$

Whakahekea te hautanga \frac{36}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{12}{5}$$
