Whakaoti i te -(x-2)+3(x-1)+2=0

$$- ( x - 2 ) + 3 ( x - 1 ) + 2 = 0$$

Whakaoti mō x

$$x=-\frac{1}{2}=-0.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o x-2, kimihia te tauaro o ia taurangi.

$$-x-\left(-2\right)+3\left(x-1\right)+2=0$$

Ko te tauaro o -2 ko 2.

$$-x+2+3\left(x-1\right)+2=0$$

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

$$-x+2+3x-3+2=0$$

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

$$2x+2-3+2=0$$

Tangohia te 3 i te 2, ka -1.

$$2x-1+2=0$$

Tāpirihia te -1 ki te 2, ka 1.

$$2x+1=0$$

Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$2x=-1$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{-1}{2}$$

Ka taea te hautanga \frac{-1}{2} te tuhi anō ko -\frac{1}{2} mā te tango i te tohu tōraro.

$$x=-\frac{1}{2}$$
