Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Me tāpiri te 5r ki ngā taha e rua.

$$-8r-3+5r=9$$

Pahekotia te -8r me 5r, ka -3r.

$$-3r-3=9$$

Me tāpiri te 3 ki ngā taha e rua.

$$-3r=9+3$$

Tāpirihia te 9 ki te 3, ka 12.

$$-3r=12$$

Whakawehea ngā taha e rua ki te -3.

$$r=\frac{12}{-3}$$

Whakawehea te 12 ki te -3, kia riro ko -4.

$$r=-4$$

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