Whakaoti i te {l}{1/2varphi=1/4x}{1/4x=5}

$$\left. \begin{array} { l } { \frac { 1 } { 2 } \varphi = \frac { 1 } { 4 } x } \\ { \frac { 1 } { 4 } x = 5 } \end{array} \right.$$

Whakaoti mō φ, x

$$x=20$$

$$\phi =10$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Me whakarea ngā taha e rua ki te 4, te tau utu o \frac{1}{4}.

$$x=5\times 4$$

Whakareatia te 5 ki te 4, ka 20.

$$x=20$$

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

$$\frac{1}{2}\phi =\frac{1}{4}\times 20$$

Whakareatia te \frac{1}{4} ki te 20, ka 5.

$$\frac{1}{2}\phi =5$$

Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.

$$\phi =5\times 2$$

Whakareatia te 5 ki te 2, ka 10.

$$\phi =10$$

Kua oti te pūnaha te whakatau.

$$\phi =10 x=20$$
