Whakaoti i te x+x-1=1/2

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

Whakaoti mō x

$$x=\frac{3}{4}=0.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te x me x, ka 2x.

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

Me tāpiri te 1 ki ngā taha e rua.

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

Me tahuri te 1 ki te hautau \frac{2}{2}.

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

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{2}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te 1 ki te 2, ka 3.

$$2x=\frac{3}{2}$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{\frac{3}{2}}{2}$$

Tuhia te \frac{\frac{3}{2}}{2} hei hautanga kotahi.

$$x=\frac{3}{2\times 2}$$

Whakareatia te 2 ki te 2, ka 4.

$$x=\frac{3}{4}$$
