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

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

Whakaoti mō x

$$x=-6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+4.

$$6x+8-3\left(x-1\right)=x-1$$

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

$$6x+8-3x+3=x-1$$

Pahekotia te 6x me -3x, ka 3x.

$$3x+8+3=x-1$$

Tāpirihia te 8 ki te 3, ka 11.

$$3x+11=x-1$$

Tangohia te x mai i ngā taha e rua.

$$3x+11-x=-1$$

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

$$2x+11=-1$$

Tangohia te 11 mai i ngā taha e rua.

$$2x=-1-11$$

Tangohia te 11 i te -1, ka -12.

$$2x=-12$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{-12}{2}$$

Whakawehea te -12 ki te 2, kia riro ko -6.

$$x=-6$$
