Whakaarohia te whārite tuatahi. Tangohia te 0.4 i te \frac{3}{5}, ka \frac{1}{5}.

$$0.875-\frac{1}{5}x=\frac{\frac{3}{16}}{0.3}$$

Tuhia te \frac{\frac{3}{16}}{0.3} hei hautanga kotahi.

$$0.875-\frac{1}{5}x=\frac{3}{16\times 0.3}$$

Whakareatia te 16 ki te 0.3, ka 4.8.

$$0.875-\frac{1}{5}x=\frac{3}{4.8}$$

Whakarohaina te \frac{3}{4.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$0.875-\frac{1}{5}x=\frac{30}{48}$$

Whakahekea te hautanga \frac{30}{48} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$0.875-\frac{1}{5}x=\frac{5}{8}$$

Tangohia te 0.875 mai i ngā taha e rua.

$$-\frac{1}{5}x=\frac{5}{8}-0.875$$

Tangohia te 0.875 i te \frac{5}{8}, ka -\frac{1}{4}.

$$-\frac{1}{5}x=-\frac{1}{4}$$

Me whakarea ngā taha e rua ki te -5, te tau utu o -\frac{1}{5}.

$$x=-\frac{1}{4}\left(-5\right)$$

Whakareatia te -\frac{1}{4} ki te -5, ka \frac{5}{4}.

$$x=\frac{5}{4}$$

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

$$y=\frac{5}{4}$$

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

$$z=\frac{5}{4}$$

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

$$a=\frac{5}{4}$$

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

$$b=\frac{5}{4}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{5}{4} y=\frac{5}{4} z=\frac{5}{4} a=\frac{5}{4} b=\frac{5}{4}$$
