a) 5x+4>4x+24 ==> 5x - 4x > 24 - 4 ==> x > 20
b) 24x>x-10 ==> 24x-x > - 10 ==> 23x > - 10 ==> x > - 10/23
c) 3 (x+2) <3. (1-x) ==> 3x+6 < 3 - 3x ==> 3x+3x < 3 -6 ==> 6x < - 3 ==> x < - 3/6
d) x/3- (x+1/2) < (1-x/2) mmc = 6
2x - 6x - 3 < 6 - 3x
2x - 6x + 3x < 6 + 3
- x < 9 (-1)
x > - 9
e) 4. (2x+3) <6. (x+4)
8x + 12 < 6x + 24
8x - 6x < 24 - 12
