Answer:
x=-16
Step-by-step explanation:
We are given with the equation
We are asked to solve it for x.
Distributing 
over bracket and simplifying
Adding 8 on both sides
Dividing both sides by -3
You need to simplify so one-fifth would be 3/15 and 2/3 would be 10/15 so you need to add that together and it would be 13/15
-(-2-5x)+(-2)=18
2+5x-2=18
5x=18
x=18/5=3.6
