Whakaoti i te 16-03/2y+44+15/5y<-405y

$$\frac { 16 - 03 } { 2 } y + \frac { 44 + 15 } { 5 } y < - 405 y$$

Whakaoti mō y

$$y<0$$

Ngā Upane Otinga

Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 2,5. I te mea he tōrunga te 10, kāore e huri te ahunga koreōrite.

$$5\left(16-0\times 3\right)y+2\left(44+15\right)y<-4050y$$

Whakareatia te 0 ki te 3, ka 0.

$$5\left(16-0\right)y+2\left(44+15\right)y<-4050y$$

Tangohia te 0 i te 16, ka 16.

$$5\times 16y+2\left(44+15\right)y<-4050y$$

Whakareatia te 5 ki te 16, ka 80.

$$80y+2\left(44+15\right)y<-4050y$$

Tāpirihia te 44 ki te 15, ka 59.

$$80y+2\times 59y<-4050y$$

Whakareatia te 2 ki te 59, ka 118.

$$80y+118y<-4050y$$

Pahekotia te 80y me 118y, ka 198y.

$$198y<-4050y$$

Me tāpiri te 4050y ki ngā taha e rua.

$$198y+4050y<0$$

Pahekotia te 198y me 4050y, ka 4248y.

$$4248y<0$$

Ko te otinga o ngā tau e rua ko <0 ina ko >0 tētahi, ā, ko <0 tētahi. Ina ko 4248>0, he <0 rawa a y.

$$y<0$$
