Answer to Problem 13P
The required answer is: consecutive even integers are 4, 6, 8 and 10
Explanation of Solution
Calculation:
Let the first even integer be x
Let the second even integer be x+2
Let the third even integer be x+4
Let the fourth even integer be x+6
(Fourth is the sum of first and second)
(Subtract x from both sides)
(Subtract 2 from both sides)
(Simplify)
First even integer:
Second even integer:
Third even integer:
Fourth even integer:
Therefore the consecutive even integers are 4, 6, 8 and 10.
