Whakareatia te 4.184 ki te 1000, ka 4184.

$$4184\left(-50\right)+2\times 800\times 20+x\times 333.3+x\times 4.184\times 0=0$$

Whakareatia te 4184 ki te -50, ka -209200.

$$-209200+2\times 800\times 20+x\times 333.3+x\times 4.184\times 0=0$$

Whakareatia te 2 ki te 800, ka 1600.

$$-209200+1600\times 20+x\times 333.3+x\times 4.184\times 0=0$$

Whakareatia te 1600 ki te 20, ka 32000.

$$-209200+32000+x\times 333.3+x\times 4.184\times 0=0$$

Tāpirihia te -209200 ki te 32000, ka -177200.

$$-177200+x\times 333.3+x\times 4.184\times 0=0$$

Whakareatia te 4.184 ki te 0, ka 0.

$$-177200+x\times 333.3+x\times 0=0$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$-177200+x\times 333.3+0=0$$

Tāpirihia te -177200 ki te 0, ka -177200.

$$-177200+x\times 333.3=0$$

Me tāpiri te 177200 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$x\times 333.3=177200$$

Whakawehea ngā taha e rua ki te 333.3.

$$x=\frac{177200}{333.3}$$

Whakarohaina te \frac{177200}{333.3} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{1772000}{3333}$$
