Whakaoti i te 37-(3x+2(x-4))=15

$$37 - ( 3 x + 2 ( x - 4 ) ) = 15$$

Whakaoti mō x

$$x=6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-4.

$$37-\left(3x+2x-8\right)=15$$

Pahekotia te 3x me 2x, ka 5x.

$$37-\left(5x-8\right)=15$$

Hei kimi i te tauaro o 5x-8, kimihia te tauaro o ia taurangi.

$$37-5x-\left(-8\right)=15$$

Ko te tauaro o -8 ko 8.

$$37-5x+8=15$$

Tāpirihia te 37 ki te 8, ka 45.

$$45-5x=15$$

Tangohia te 45 mai i ngā taha e rua.

$$-5x=15-45$$

Tangohia te 45 i te 15, ka -30.

$$-5x=-30$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{-30}{-5}$$

Whakawehea te -30 ki te -5, kia riro ko 6.

$$x=6$$
