Whakaoti i te 1/3x-1/2=2

$$\frac { 1 } { 3 } x - \frac { 1 } { 2 } = 2$$

Whakaoti mō x

$$x = \frac{15}{2} = 7\frac{1}{2} = 7.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te \frac{1}{2} ki ngā taha e rua.

$$\frac{1}{3}x=2+\frac{1}{2}$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$\frac{1}{3}x=\frac{4}{2}+\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{4}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1}{3}x=\frac{4+1}{2}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{1}{3}x=\frac{5}{2}$$

Me whakarea ngā taha e rua ki te 3, te tau utu o \frac{1}{3}.

$$x=\frac{5}{2}\times 3$$

Tuhia te \frac{5}{2}\times 3 hei hautanga kotahi.

$$x=\frac{5\times 3}{2}$$

Whakareatia te 5 ki te 3, ka 15.

$$x=\frac{15}{2}$$
