Answer:
x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)
Explanation:
We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...
9*-5x = -45x
9*-2 = -18
-45x = -18
Now, divide both sides by 45...
-45x/45 = -18/45
x = 18/45 should be the answer.
