Answer:
1st number = 26
2nd number = -57
Explanation:
Sum = -31
One number = x
Second number = x - 83
=> x + x - 83 = -31
=> 2x - 83 = -31
=> 2x - 83 + 83 = -31 + 83
=> 2x = 52
=> 2x/2 = 52/2
=> x = 26
First number = x = 26
Second number = x - 83 = 26 - 83 = -57
So, the 1st number = 26
2nd number = -57
