Whakaoti i te {l}{x+y=36}{5/7=x/4}

$$\left\{ \begin{array} { l } { x + y = 36 } \\ { \frac { 5 } { 7 } = \frac { x } { 4 } } \end{array} \right.$$

Whakaoti mō x, y

$$x = \frac{20}{7} = 2\frac{6}{7} \approx 2.857142857$$

$$y = \frac{232}{7} = 33\frac{1}{7} \approx 33.142857143$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Me whakarea ngā taha e rua ki te 4.

$$\frac{5}{7}\times 4=x$$

Whakareatia te \frac{5}{7} ki te 4, ka \frac{20}{7}.

$$\frac{20}{7}=x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x=\frac{20}{7}$$

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

$$\frac{20}{7}+y=36$$

Tangohia te \frac{20}{7} mai i ngā taha e rua.

$$y=36-\frac{20}{7}$$

Tangohia te \frac{20}{7} i te 36, ka \frac{232}{7}.

$$y=\frac{232}{7}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{20}{7} y=\frac{232}{7}$$
