Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.

$$2\left(r-6\right)=r+3$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te r-6.

$$2r-12=r+3$$

Tangohia te r mai i ngā taha e rua.

$$2r-12-r=3$$

Pahekotia te 2r me -r, ka r.

$$r-12=3$$

Me tāpiri te 12 ki ngā taha e rua.

$$r=3+12$$

Tāpirihia te 3 ki te 12, ka 15.

$$r=15$$

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

$$s=7\times 15+6$$

Whakareatia te 7 ki te 15, ka 105.

$$s=105+6$$

Tāpirihia te 105 ki te 6, ka 111.

$$s=111$$

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

$$t=111$$

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

$$u=111$$

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

$$v=111$$

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

$$w=111$$

Kua oti te pūnaha te whakatau.

$$r=15 s=111 t=111 u=111 v=111 w=111$$
