What happens if you get 7x + 3 < 0 ?
Do you write to equations like:
1) 7x + 3 < 0 and 7x + 3> 0 ?
But then you get an answers like x> -3/7 or x< -3/7 and it doesnt make any sense?

-
7x + 3 < 0
7x < - 3
x < - 3/7, answer!
7x + 3 > 0
7x > - 3
x > - 3/7, answer!
7x < - 3
x < - 3/7, answer!
7x + 3 > 0
