Whakaoti i te 2-3x-1/5=-4

$$2 - \frac { 3 x - 1 } { 5 } = - 4$$

Whakaoti mō x

$$x = \frac{31}{3} = 10\frac{1}{3} \approx 10.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 5.

$$10-\left(3x-1\right)=-20$$

Hei kimi i te tauaro o 3x-1, kimihia te tauaro o ia taurangi.

$$10-3x-\left(-1\right)=-20$$

Ko te tauaro o -1 ko 1.

$$10-3x+1=-20$$

Tāpirihia te 10 ki te 1, ka 11.

$$11-3x=-20$$

Tangohia te 11 mai i ngā taha e rua.

$$-3x=-20-11$$

Tangohia te 11 i te -20, ka -31.

$$-3x=-31$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{-31}{-3}$$

Ka taea te hautanga \frac{-31}{-3} te whakamāmā ki te \frac{31}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{31}{3}$$
