1/4(5x-1/2)-5/3<1/3

5/4x-1/8-5/3<1/3

24(5/4x-1/8-5/3)<24(1/3)

30x-3-40<8

30x-43+43<8+43

30x<51

x<51/30

{x|x<51/30}

31-(2x+2)< or equal to 4(x+1)+x

31-2x-2< equal to 4x+4+x

29-2x<equal to 5x+4

-2x<equal to 5x-25

-7x<equal to -25

{x|x>equal to 3.6}

Use elimination method: 4x+5y=-12 and 7x-5y=-76 I got x=-8 and y=4

elimination: 0.3x-0.2y=4 and 0.4x+0.5y=1 I got the solution of (220/23,-130/23)
