3/4(3+2x)+2>17
multiply each term by 4
3(3+2x) + 8 > 68
9 + 6x > 60
6x > 51
x > 51/6
the second is really easy, add 12 to both sides, then divide by 8

That is what I did but I was told it was wrong...I got 3/8

8x12<9
8x < 129
8x < 3
x < 3/8
Was there a restriction on x, e.g. did it say x is an element of the integers or something like that?
