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

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

Whakaoti mō x

$$x=6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2x-4-\left(4x-1\right)=3\left(1-x\right)$$

Hei kimi i te tauaro o 4x-1, kimihia te tauaro o ia taurangi.

$$2x-4-4x-\left(-1\right)=3\left(1-x\right)$$

Ko te tauaro o -1 ko 1.

$$2x-4-4x+1=3\left(1-x\right)$$

Pahekotia te 2x me -4x, ka -2x.

$$-2x-4+1=3\left(1-x\right)$$

Tāpirihia te -4 ki te 1, ka -3.

$$-2x-3=3\left(1-x\right)$$

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

$$-2x-3=3-3x$$

Me tāpiri te 3x ki ngā taha e rua.

$$-2x-3+3x=3$$

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

$$x-3=3$$

Me tāpiri te 3 ki ngā taha e rua.

$$x=3+3$$

Tāpirihia te 3 ki te 3, ka 6.

$$x=6$$
