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

$$s=\frac{\left(-4-5\right)\times 4}{2}$$

Tangohia te 5 i te -4, ka -9.

$$s=\frac{-9\times 4}{2}$$

Whakareatia te -9 ki te 4, ka -36.

$$s=\frac{-36}{2}$$

Whakawehea te -36 ki te 2, kia riro ko -18.

$$s=-18$$

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

$$w=-18$$

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

$$x=-18$$

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

$$y=-18$$

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

$$z=-18$$

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

$$a=-18$$

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

$$b=-18$$

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

$$c=-18$$

Kua oti te pūnaha te whakatau.
