Hi, there--
.
To solve this problem we need to translate English phrases into algebraic expressions. Then we write an equation showing the relationship between the integers.
.
Let's call the first integer n.
The second integer is n+1 since the two integers are consecutive.
Likewise, the third integer is n+2 because (n+1)+1=n+2.
.
We write "the sum of the first two integers" as n+(n+1).
We write "23 more than the third" as (n+2)+23.
.
These two expression have the same value, so
[sum of the first two integers] = [23 more than the third]
.
Our equation is
n%2B%28n%2B1%29=%28n%2B2%29%2B23
.
Simplify by combining like terms.
2n%2B1=n%2B25
.
Subtract n from both sides of the equation to isolate the n-term on the left side.
n%2B1=25
.
Subtract 1 from both sides of the equation to isolate the constant term on the right side.
n=24
.
We see that the first integer is n=24. Therefore, the other two integers are 25, and 26.
.
Always take time to check your work.
Are the first two integers 23 more than the third? 24+25=49 and 49-26=23...Yes!
.
That's it! Feel free to email me if this explanation is unclear.
