-2-2x≤2
To solve an inequality, it's just like an equation, first add 2 to both sides to get
-2x≤4
Divide both sides by -2to get
x≥-2
When you divide by a negative number, you flip the sign.
Your solution is x≥-2.
Hope this helped!

This is not a full question. If you were given the amount at the begining of 1970 (we'll call it x) and the amount at the end of 1980 (we'll call it y), we should solve them accordingly:
y-x=? (calling the answer a)
a/y=%(not answer yet, call this b)
b+100=answer
