All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Ok!
The answer is a = -170.
First, multiply 20 on both sides.
Next, add the 10 on both sides. This will leave you with a being equal to -170 :)
