b. x+10>6   x>-4  x=-3, -2, -1, 0, 1, 2, ...

c. x+18<sau egal 2  x<sau egal -16  x=..., -18, -17, -16

d. x+14>sau egal 7  x>sau egal -7   x=-7, -6, -5, ..., 0, 1, 2, ...

e. -x-4>-7  -x>-3  x<3   x=..., -3, -2, -1, 0, 1, 2

f. -x+2<sau egal -2  -x<sau egal -4  x>sau egal 4  x=4, 5, 6, ...

g. -7x>sau egal -14   x<sau egal 2   x=..., -3, -2, -1, 0, 1, 2

h. -6x<-30  -x<-5  x>5   x= 6, 7, 8, ...
