Whakaoti i te 200*0.22*(-6)+120(-6)+x*0.22*80=0

$$200 \times 0.22 \times ( - 6 ) + 120 ( - 6 ) + x \times 0.22 \times 80 = 0$$

Whakaoti mō x

$$x = \frac{615}{11} = 55\frac{10}{11} \approx 55.909090909$$

Whakareatia te 200 ki te 0.22, ka 44.

$$44\left(-6\right)+120\left(-6\right)+x\times 0.22\times 80=0$$

Whakareatia te 44 ki te -6, ka -264.

$$-264+120\left(-6\right)+x\times 0.22\times 80=0$$

Whakareatia te 120 ki te -6, ka -720.

$$-264-720+x\times 0.22\times 80=0$$

Tangohia te 720 i te -264, ka -984.

$$-984+x\times 0.22\times 80=0$$

Whakareatia te 0.22 ki te 80, ka 17.6.

$$-984+x\times 17.6=0$$

Me tāpiri te 984 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$x\times 17.6=984$$

Whakawehea ngā taha e rua ki te 17.6.

$$x=\frac{984}{17.6}$$

Whakarohaina te \frac{984}{17.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{9840}{176}$$

Whakahekea te hautanga \frac{9840}{176} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$x=\frac{615}{11}$$
