Whakaoti i te 3/4=2/3y-1/2y

$$\frac { 3 } { 4 } = \frac { 2 } { 3 } y - \frac { 1 } { 2 } y$$

Whakaoti mō y

$$y = \frac{9}{2} = 4\frac{1}{2} = 4.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te \frac{2}{3}y me -\frac{1}{2}y, ka \frac{1}{6}y.

$$\frac{3}{4}=\frac{1}{6}y$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{1}{6}y=\frac{3}{4}$$

Me whakarea ngā taha e rua ki te 6, te tau utu o \frac{1}{6}.

$$y=\frac{3}{4}\times 6$$

Tuhia te \frac{3}{4}\times 6 hei hautanga kotahi.

$$y=\frac{3\times 6}{4}$$

Whakareatia te 3 ki te 6, ka 18.

$$y=\frac{18}{4}$$

Whakahekea te hautanga \frac{18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$y=\frac{9}{2}$$
