Whakaoti i te 6-x=4(x-3)-7(x-4)

$$6 - x = 4 ( x - 3 ) - 7 ( x - 4 )$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-3.

$$6-x=4x-12-7\left(x-4\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x-4.

$$6-x=4x-12-7x+28$$

Pahekotia te 4x me -7x, ka -3x.

$$6-x=-3x-12+28$$

Tāpirihia te -12 ki te 28, ka 16.

$$6-x=-3x+16$$

Me tāpiri te 3x ki ngā taha e rua.

$$6-x+3x=16$$

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

$$6+2x=16$$

Tangohia te 6 mai i ngā taha e rua.

$$2x=16-6$$

Tangohia te 6 i te 16, ka 10.

$$2x=10$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{10}{2}$$

Whakawehea te 10 ki te 2, kia riro ko 5.

$$x=5$$
