Whakaoti i te 6-2(x-1)=4/5

$$6 - 2 ( x - 1 ) = \frac { 4 } { 5 }$$

Whakaoti mō x

$$x = \frac{18}{5} = 3\frac{3}{5} = 3.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.

$$6-2x+2=\frac{4}{5}$$

Tāpirihia te 6 ki te 2, ka 8.

$$8-2x=\frac{4}{5}$$

Tangohia te 8 mai i ngā taha e rua.

$$-2x=\frac{4}{5}-8$$

Me tahuri te 8 ki te hautau \frac{40}{5}.

$$-2x=\frac{4}{5}-\frac{40}{5}$$

Tā te mea he rite te tauraro o \frac{4}{5} me \frac{40}{5}, me tango rāua mā te tango i ō raua taurunga.

$$-2x=\frac{4-40}{5}$$

Tangohia te 40 i te 4, ka -36.

$$-2x=-\frac{36}{5}$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-\frac{36}{5}}{-2}$$

Tuhia te \frac{-\frac{36}{5}}{-2} hei hautanga kotahi.

$$x=\frac{-36}{5\left(-2\right)}$$

Whakareatia te 5 ki te -2, ka -10.

$$x=\frac{-36}{-10}$$

Whakahekea te hautanga \frac{-36}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.

$$x=\frac{18}{5}$$
