Whakaoti i te 3(2x-1)-1=-4(x-4)

$$3 ( 2 x - 1 ) - 1 = - 4 ( x - 4 )$$

Whakaoti mō x

$$x=2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-1.

$$6x-3-1=-4\left(x-4\right)$$

Tangohia te 1 i te -3, ka -4.

$$6x-4=-4\left(x-4\right)$$

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

$$6x-4=-4x+16$$

Me tāpiri te 4x ki ngā taha e rua.

$$6x-4+4x=16$$

Pahekotia te 6x me 4x, ka 10x.

$$10x-4=16$$

Me tāpiri te 4 ki ngā taha e rua.

$$10x=16+4$$

Tāpirihia te 16 ki te 4, ka 20.

$$10x=20$$

Whakawehea ngā taha e rua ki te 10.

$$x=\frac{20}{10}$$

Whakawehea te 20 ki te 10, kia riro ko 2.

$$x=2$$
