Whakaoti i te 3(x-4)=5(x+8)

$$3(x-4)=5(x+8)$$

Whakaoti mō x

$$x=-26$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$3x-12=5\left(x+8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+8.

$$3x-12=5x+40$$

Tangohia te 5x mai i ngā taha e rua.

$$3x-12-5x=40$$

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

$$-2x-12=40$$

Me tāpiri te 12 ki ngā taha e rua.

$$-2x=40+12$$

Tāpirihia te 40 ki te 12, ka 52.

$$-2x=52$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{52}{-2}$$

Whakawehea te 52 ki te -2, kia riro ko -26.

$$x=-26$$
