Whakaoti i te {l}{6.65A+2.705=806.10}{7A+S=202}

$$\left\{ \begin{array} { l } { 6.65 A + 2.705 = 806.10 } \\ { 7 A + S = 202 } \end{array} \right.$$

Whakaoti mō A, S

$$A = \frac{160679}{1330} = 120\frac{1079}{1330} \approx 120.811278195$$

$$S = -\frac{122299}{190} = -643\frac{129}{190} \approx -643.678947368$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 2.705 mai i ngā taha e rua.

$$6.65A=806.1-2.705$$

Tangohia te 2.705 i te 806.1, ka 803.395.

$$6.65A=803.395$$

Whakawehea ngā taha e rua ki te 6.65.

$$A=\frac{803.395}{6.65}$$

Whakarohaina te \frac{803.395}{6.65} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$A=\frac{803395}{6650}$$

Whakahekea te hautanga \frac{803395}{6650} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$A=\frac{160679}{1330}$$

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

$$7\times \frac{160679}{1330}+S=202$$

Whakareatia te 7 ki te \frac{160679}{1330}, ka \frac{160679}{190}.

$$\frac{160679}{190}+S=202$$

Tangohia te \frac{160679}{190} mai i ngā taha e rua.

$$S=202-\frac{160679}{190}$$

Tangohia te \frac{160679}{190} i te 202, ka -\frac{122299}{190}.

$$S=-\frac{122299}{190}$$

Kua oti te pūnaha te whakatau.

$$A=\frac{160679}{1330} S=-\frac{122299}{190}$$
