2x + 28 < with a line under it _ <_ 6x
sorry don't know how to add that special character in, but it is only one thing like the +
between the 28 and 6

2X + 28 <= 6X
And playing with this, we have:
28 <= 6X - 2X = 4X; so that 7 <= X
Suppose we multiply 7 <= X by minus one on both sides; what would that give us? Be careful, the answer is not that obvious.
