Hi,
For this question, distribute the -5 over the factor m + 3 to get:
-5m - 15 = 45
Now, add 15 to both sides of the equation to get:
-5m = 60
Now, we need to isolate for m alone by dividing both sides of the equation by -5 to get:
FINAL ANSWER: m = -12 or answer choice D
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

Divide both sides by 5. Then subtract 3.
-5(m +3) / -5 = m+ 3
45 / -5 = -9
Gets you m+3=-9
m + 3 - 3 = m
-9 - 3 = -12
Gets you M = -12

-5m-15=45
-5m= 45+15
-5m=60
m=-12
answer is D
