Question 829367: The sum of 2 consecutive integers is -22, what are the 2 intergers?
Answer by JulietG(1812) (Show Source): You can put this solution on YOUR website!
Let x be the first integer
The second integer is therefore x+1
We're told that x + (x+1) = -22
Add the Xs
2x + 1 = -22
subtract 1 from each side
2x = -23
Divide each side by 2
x = -11.5
.
OOPS. There's a problem somewhere. -11.5 is not an integer (an integer is a whole number). Can you doublecheck your values?
.
-10 + -11 = -21
-11 + -12 = -23
Your value lies between them.
.
I wonder if the question is actually consecutive EVEN integers? In that case:
x + (x+2) = -22
2x + 2 = -22
2x =-20
x = -10
In that case, one integer is -10 and the other -12.
