Question 1137273
Two consecutive integers add to make 315.
Jamal writes expressions for the two integers:
1st number n, 2nd number n+2 
------------------

"Two consecutive integers" should be  n  and n+1  (not n and n+2)<br>

<pre>
a)  n + (n+1) = 2n+1

b)  2n + 1 = 315

c)  2n + 1 = 315

 Subtract 1 from both sides, then...
 Divide both sides by 2...
  now you will have the value of n

Step (d) is then trivial
