What is written in the post by @consc198, is precisely opposite to what is written in the incoming post.
So the meaning WHY he wrote it is dark and unclear.
If you want we, the tutors, solve it for you, here is the solution:
Subtract 2x and 18 from both sides. You will get an equivalent inequality
-18 >= 5x - 2x,
-18 >= 3x
x <= -18/3
x <= -6.
ANSWER. The solution to the given inequality is the set of real numbers x <= -6.
Solved completely, with step-by-step explanations.
For the sign "greater or equal" use a standard symbol " >= ".
