I'm a retired physician available to tutor math (algebra 1)
The answer is -48 = (-17) + (-16) + (-15)
Here is how I did it:
Let a represent the first integer in the 3 integer series
The second integer will be one greater than a, represented as (a+1)
The third integer will be two greater than a, represented as (a+2)
Now, we can write the equation below:
-48 = a + (a+1) + (a+2)
Now group the a's and the numbers
-48 = 3a + 3
Subtract 3 from both sides
-51 = 3a
Divide both sides by 3
-17 = a
So the first integer in the series is -17
Add positive 1 to get the second integer: -17 + 1 = -16
Add positive 2 to get the third integer: -17 + 2 = -15
Hope that helps

After posting my answer I realized the question was asking for 3 consecutive EVEN integers with a sum of -48. My answer was for 3 consecutive integers (even or odd) with a sum of -48. Sorry for any confusion.12/08/20
