$$c = -\frac{15}{2} = -7\frac{1}{2} = -7.5$$

$$d = -\frac{15}{2} = -7\frac{1}{2} = -7.5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tāpirihia te 6 ki te 1, ka 7.

$$x=7$$

Whakaarohia te whārite tuarua. Tangohia te 1 i te -2, ka -3.

$$y=-3$$

Whakaarohia te whārite tuatoru. Tāpirihia te -4 ki te 1, ka -3.

$$0=-3-2t$$

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

$$-3-2t=0$$

Me tāpiri te 3 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$-2t=3$$

Whakawehea ngā taha e rua ki te -2.

$$t=-\frac{3}{2}$$

Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$u=5\left(-\frac{3}{2}\right)$$

Whakareatia te 5 ki te -\frac{3}{2}, ka -\frac{15}{2}.

$$u=-\frac{15}{2}$$

Whakaarohia te whārite tuarima. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$v=5\left(-\frac{3}{2}\right)$$

Whakareatia te 5 ki te -\frac{3}{2}, ka -\frac{15}{2}.

$$v=-\frac{15}{2}$$

Whakaarohia te whārite (6). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$w=-\frac{15}{2}$$

Whakaarohia te whārite (7). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$z=-\frac{15}{2}$$

Whakaarohia te whārite (8). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$a=-\frac{15}{2}$$

Whakaarohia te whārite (9). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=-\frac{15}{2}$$

Whakaarohia te whārite (10). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$c=-\frac{15}{2}$$

Whakaarohia te whārite (11). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$d=-\frac{15}{2}$$

Kua oti te pūnaha te whakatau.
