Whakaoti i te 12*1.5-4*x=0.5*0.4*5

$$12 \times 1.5-4 \times x=0.5 \times 0.4 \times 5$$

Whakaoti mō x

$$x=4.25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 12 ki te 1.5, ka 18.

$$18-4x=0.5\times 0.4\times 5$$

Whakareatia te 0.5 ki te 0.4, ka 0.2.

$$18-4x=0.2\times 5$$

Whakareatia te 0.2 ki te 5, ka 1.

$$18-4x=1$$

Tangohia te 18 mai i ngā taha e rua.

$$-4x=1-18$$

Tangohia te 18 i te 1, ka -17.

$$-4x=-17$$

Whakawehea ngā taha e rua ki te -4.

$$x=\frac{-17}{-4}$$

Ka taea te hautanga \frac{-17}{-4} te whakamāmā ki te \frac{17}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{17}{4}$$
