Hello,
Here's my solution:
Let n = the lesser of the two consecutive even integers; so what will be a good way to represent the greater of the two consecutive even integers? I say n + 2.
Let's write the equation:
n = ((n+2)/2) + 10
I'll multiply both sides of the equation by 2 to eliminate the denominator, getting:
2n = 2[((n+2)/2) + 10]
This reduces to:
2n = n+2 + 20
Which can be further simplified to:
2n = n+22
Subtracting n from both sides we get:
n = 22
So n, the lesser consecutive even integer is 22. The greater consecutive even integer is 24.
Let's check this solution by substituting n = 22 into our original equation:
n = ((n+2)/2) + 10
22 = ((22+2)/2) + 10
22 = ((24)/2) + 10
22 = (12) + 10
22 = 22 - it checks!
