Answer:
The answer is a= 8
Explanation:
You want to first do the number in parenthesis.
That's -5 • a = -5a
Then you multiply -5 • 3 = -15
Your new equation would be -5a -15 = -55
You add 15 to the -15 and the -55 that would be
-5a = -40
At the end you divide -5a÷ -5 = a
If you do this to one side you have to do it to the other.
-40÷ -5 = 8
a=8
