Whakaoti i te (x-60)(120-05x)=1600

$$( x - 60 ) ( 120 - 05 x ) = 1600$$

Whakaoti mō x

$$x = \frac{220}{3} = 73\frac{1}{3} \approx 73.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0 ki te 5, ka 0.

$$\left(x-60\right)\left(120-0x\right)=1600$$

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

$$\left(x-60\right)\left(120-0\right)=1600$$

Tangohia te 0 i te 120, ka 120.

$$\left(x-60\right)\times 120=1600$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-60 ki te 120.

$$120x-7200=1600$$

Me tāpiri te 7200 ki ngā taha e rua.

$$120x=1600+7200$$

Tāpirihia te 1600 ki te 7200, ka 8800.

$$120x=8800$$

Whakawehea ngā taha e rua ki te 120.

$$x=\frac{8800}{120}$$

Whakahekea te hautanga \frac{8800}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.

$$x=\frac{220}{3}$$
