Hi Conny;
x=first integer
x+1=second integer
x+2=third integer
 
(x)+(x+1)+(x+2)=63
3x+3=63
Let's subtract 3 from both sides to proceed to isolate x...
-3+3x+3=63-3
3x=60
Let's divide both sides by 3...
3x/3=60/3
x=20
 
Let's check our work...
x=20
x+1=21
x+2=22
Does 20+21+22=63
Yes!

Vivian...Correct for 3 consecutive numbers but it was supposed to be 3 consecutive odd integers.
Thank you.
I missed the word "odd".
