Whakaoti i te {l}{2m+m=7}{2n+m=2}

$$\left\{ \begin{array} { l } { 2 m + m = 7 } \\ { 2 n + m = 2 } \end{array} \right.$$

Whakaoti mō m, n

$$m = \frac{7}{3} = 2\frac{1}{3} \approx 2.333333333$$

$$n=-\frac{1}{6}\approx -0.166666667$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Pahekotia te 2m me m, ka 3m.

$$3m=7$$

Whakawehea ngā taha e rua ki te 3.

$$m=\frac{7}{3}$$

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

$$2n+\frac{7}{3}=2$$

Tangohia te \frac{7}{3} mai i ngā taha e rua.

$$2n=2-\frac{7}{3}$$

Tangohia te \frac{7}{3} i te 2, ka -\frac{1}{3}.

$$2n=-\frac{1}{3}$$

Whakawehea ngā taha e rua ki te 2.

$$n=\frac{-\frac{1}{3}}{2}$$

Tuhia te \frac{-\frac{1}{3}}{2} hei hautanga kotahi.

$$n=\frac{-1}{3\times 2}$$

Whakareatia te 3 ki te 2, ka 6.

$$n=\frac{-1}{6}$$

Ka taea te hautanga \frac{-1}{6} te tuhi anō ko -\frac{1}{6} mā te tango i te tohu tōraro.

$$n=-\frac{1}{6}$$

Kua oti te pūnaha te whakatau.

$$m=\frac{7}{3} n=-\frac{1}{6}$$
