Whakaoti i te 3/2-2y=7

$$\frac { 3 } { 2 } - 2 y = 7$$

Whakaoti mō y

$$y = -\frac{11}{4} = -2\frac{3}{4} = -2.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{3}{2} mai i ngā taha e rua.

$$-2y=7-\frac{3}{2}$$

Me tahuri te 7 ki te hautau \frac{14}{2}.

$$-2y=\frac{14}{2}-\frac{3}{2}$$

Tā te mea he rite te tauraro o \frac{14}{2} me \frac{3}{2}, me tango rāua mā te tango i ō raua taurunga.

$$-2y=\frac{14-3}{2}$$

Tangohia te 3 i te 14, ka 11.

$$-2y=\frac{11}{2}$$

Whakawehea ngā taha e rua ki te -2.

$$y=\frac{\frac{11}{2}}{-2}$$

Tuhia te \frac{\frac{11}{2}}{-2} hei hautanga kotahi.

$$y=\frac{11}{2\left(-2\right)}$$

Whakareatia te 2 ki te -2, ka -4.

$$y=\frac{11}{-4}$$

Ka taea te hautanga \frac{11}{-4} te tuhi anō ko -\frac{11}{4} mā te tango i te tohu tōraro.

$$y=-\frac{11}{4}$$
