Answer:
26 and -57
Step-by-step explanation:
First write the equation (Use x for one number and x - 83 for the second):
x + x - 83 = -31
Next add 83 to both sides:
x + x - 83 + 83 = -31 + 83
x + x = 2x = 52
Now all you have to do is figure out what x is and you'll have one number, and subtract 83 to find the other number:
52/2 = x = 26
26 - 83 = -57
Now you have your answer:
26 + -57 = -31
