Whakaoti i te (2x-4)(3-6x)=(3x-5)(1-4x)

$$(2x-4)(3-6x)=(3x-5)(1-4x)$$

Whakaoti mō x

$$x=1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tuaritanga hei whakarea te 2x-4 ki te 3-6x ka whakakotahi i ngā kupu rite.

$$30x-12x^{2}-12=\left(3x-5\right)\left(1-4x\right)$$

Whakamahia te āhuatanga tuaritanga hei whakarea te 3x-5 ki te 1-4x ka whakakotahi i ngā kupu rite.

$$30x-12x^{2}-12=23x-12x^{2}-5$$

Tangohia te 23x mai i ngā taha e rua.

$$30x-12x^{2}-12-23x=-12x^{2}-5$$

Pahekotia te 30x me -23x, ka 7x.

$$7x-12x^{2}-12=-12x^{2}-5$$

Me tāpiri te 12x^{2} ki ngā taha e rua.

$$7x-12x^{2}-12+12x^{2}=-5$$

Pahekotia te -12x^{2} me 12x^{2}, ka 0.

$$7x-12=-5$$

Me tāpiri te 12 ki ngā taha e rua.

$$7x=-5+12$$

Tāpirihia te -5 ki te 12, ka 7.

$$7x=7$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{7}{7}$$

Whakawehea te 7 ki te 7, kia riro ko 1.

$$x=1$$
