Whakaoti i te (-2.3):2x-y=7

$$( - 2.3 ) : 2 x - y = 7$$

Whakaoti mō x

$$x=\frac{-20y-140}{23}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakarohaina te \frac{-2.3}{2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{-23}{20}x-y=7$$

Ka taea te hautanga \frac{-23}{20} te tuhi anō ko -\frac{23}{20} mā te tango i te tohu tōraro.

$$-\frac{23}{20}x-y=7$$

Me tāpiri te y ki ngā taha e rua.

$$-\frac{23}{20}x=7+y$$

He hanga arowhānui tō te whārite.

$$-\frac{23}{20}x=y+7$$

Whakawehea ngā taha e rua o te whārite ki te -\frac{23}{20}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-\frac{23}{20}x}{-\frac{23}{20}}=\frac{y+7}{-\frac{23}{20}}$$

Mā te whakawehe ki te -\frac{23}{20} ka wetekia te whakareanga ki te -\frac{23}{20}.

$$x=\frac{y+7}{-\frac{23}{20}}$$

Whakawehe 7+y ki te -\frac{23}{20} mā te whakarea 7+y ki te tau huripoki o -\frac{23}{20}.

$$x=\frac{-20y-140}{23}$$

Whakaoti mō y

$$y=-\frac{23x}{20}-7$$

Whakarohaina te \frac{-2.3}{2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{-23}{20}x-y=7$$

Ka taea te hautanga \frac{-23}{20} te tuhi anō ko -\frac{23}{20} mā te tango i te tohu tōraro.

$$-\frac{23}{20}x-y=7$$

Me tāpiri te \frac{23}{20}x ki ngā taha e rua.

$$-y=7+\frac{23}{20}x$$

He hanga arowhānui tō te whārite.

$$-y=\frac{23x}{20}+7$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-y}{-1}=\frac{\frac{23x}{20}+7}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$y=\frac{\frac{23x}{20}+7}{-1}$$

Whakawehe 7+\frac{23x}{20} ki te -1.

$$y=-\frac{23x}{20}-7$$
