Question

oi por favor mim ajudem 60+100x+32>80x+90+9x e 40+50x+300-60<79x+40

Answer 1

60 + 100x + 32 > 80x + 90 + 9x

60 + 32 + 100x > 80x + 9x + 90

92 + 100x > 89x + 90

100x - 89x > 90 - 92

 11x > - 2

x > - 2/11

{R.: x E R / x > - 2/11}
------------------------------------------------
40 + 50x + 300 - 60 < 79x + 40

40 + 50x + 240 < 79x + 40

50x + 240 < 79x

50x - 79x < - 240

- 29x < - 240 ( - 1)

29x > 240

x > 240/29

R.: {x E R / x > 240/29}
