Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakareatia te 0 ki te 4, ka 0.

$$0.04x=0$$

Whakawehea ngā taha e rua ki te 0.04. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$x=0$$

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

$$y=1800\times 0\times 5\times 0$$

Whakareatia te 1800 ki te 0, ka 0.

$$y=0\times 5\times 0$$

Whakareatia te 0 ki te 5, ka 0.

$$y=0\times 0$$

Whakareatia te 0 ki te 0, ka 0.

$$y=0$$

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

$$z=1800-0$$

Whakareatia te -1 ki te 0, ka 0.

$$z=1800+0$$

Tāpirihia te 1800 ki te 0, ka 1800.

$$z=1800$$

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

$$a=0$$

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

$$b=1800$$

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

$$c=0$$

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

$$d=1800$$

Kua oti te pūnaha te whakatau.

$$x=0 y=0 z=1800 a=0 b=1800 c=0 d=1800$$
