88000-4000x+2500\left(26+2x\right)<16000
Whakamahia te āhuatanga tohatoha hei whakarea te 4000 ki te 22-x.
88000-4000x+65000+5000x<16000
Whakamahia te āhuatanga tohatoha hei whakarea te 2500 ki te 26+2x.
153000-4000x+5000x<16000
Tāpirihia te 88000 ki te 65000, ka 153000.
153000+1000x<16000
Pahekotia te -4000x me 5000x, ka 1000x.
1000x<16000-153000
Tangohia te 153000 mai i ngā taha e rua.
1000x<-137000
Tangohia te 153000 i te 16000, ka -137000.
x<\frac{-137000}{1000}
Whakawehea ngā taha e rua ki te 1000. I te mea he tōrunga te 1000, kāore e huri te ahunga koreōrite.
x<-137
Whakawehea te -137000 ki te 1000, kia riro ko -137.
