Whakaoti i te 66*7+47x-8=7*2

$$66 \times 7 + 47 x - 8 = 7 \times 2$$

Whakaoti mō x

$$x = -\frac{440}{47} = -9\frac{17}{47} \approx -9.361702128$$

Whakareatia te 66 ki te 7, ka 462.

$$462+47x-8=7\times 2$$

Tangohia te 8 i te 462, ka 454.

$$454+47x=7\times 2$$

Whakareatia te 7 ki te 2, ka 14.

$$454+47x=14$$

Tangohia te 454 mai i ngā taha e rua.

$$47x=14-454$$

Tangohia te 454 i te 14, ka -440.

$$47x=-440$$

Whakawehea ngā taha e rua ki te 47.

$$x=\frac{-440}{47}$$

Ka taea te hautanga \frac{-440}{47} te tuhi anō ko -\frac{440}{47} mā te tango i te tohu tōraro.

$$x=-\frac{440}{47}$$
