4(n-2)-6> 18
-2(w+4)+9< -11
6x-13 < 6(x-2)
-7(3x-7)+21x > 50
***
4(n-2)-6> 18
4n-8-6>18
4n-14>18
4n>18+14=32
n>32/4
n>8
..
-2(w+4)+9< -11
-2w-8+9<-11
-2w+1<-11
-2w<-12
multiply both sides by (-1) and reverse inequality signs
2w>12
w>6
..
6x-13 < 6(x-2)
6x-13<6x-12
-13<-12
multiply both sides by (-1) and reverse inequality signs
13>12
..
-7(3x-7)+21x > 50
-21x+49+21x>50
49>50
no solution, not true
