Whakaoti i te {c}{12x+y=96}{(x+19/4)*16=320}

$$\left. \begin{array} { c } { 12 x + y = 96 } \\ { ( x + \frac { 19 } { 4 } ) \cdot 16 = 320 } \end{array} \right.$$

Whakaoti mō x, y

$$x = \frac{61}{4} = 15\frac{1}{4} = 15.25$$

$$y=-87$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 16.

$$x+\frac{19}{4}=\frac{320}{16}$$

Whakawehea te 320 ki te 16, kia riro ko 20.

$$x+\frac{19}{4}=20$$

Tangohia te \frac{19}{4} mai i ngā taha e rua.

$$x=20-\frac{19}{4}$$

Tangohia te \frac{19}{4} i te 20, ka \frac{61}{4}.

$$x=\frac{61}{4}$$

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

$$12\times \frac{61}{4}+y=96$$

Whakareatia te 12 ki te \frac{61}{4}, ka 183.

$$183+y=96$$

Tangohia te 183 mai i ngā taha e rua.

$$y=96-183$$

Tangohia te 183 i te 96, ka -87.

$$y=-87$$

Kua oti te pūnaha te whakatau.

$$x=\frac{61}{4} y=-87$$
