Whakaoti i te 6x-13y=-22text{tofind}ytext{if}x=11

$$6 x - 13 y = - 22 \text { to find } y \text { if } x = 11$$

Whakaoti mō x, y

$$x=11$$

$$y = \frac{88}{13} = 6\frac{10}{13} \approx 6.769230769$$

Ngā Upane Otinga

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

$$6\times 11-13y=-22$$

Whakareatia te 6 ki te 11, ka 66.

$$66-13y=-22$$

Tangohia te 66 mai i ngā taha e rua.

$$-13y=-22-66$$

Tangohia te 66 i te -22, ka -88.

$$-13y=-88$$

Whakawehea ngā taha e rua ki te -13.

$$y=\frac{-88}{-13}$$

Ka taea te hautanga \frac{-88}{-13} te whakamāmā ki te \frac{88}{13} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$y=\frac{88}{13}$$

Kua oti te pūnaha te whakatau.

$$x=11 y=\frac{88}{13}$$
