Problema Solution
Find three consecutive even integers such that the sum of the first and third is three times the second even integer minus four. What are the three numbers?
Answer provided by our tutors
the three consecutive even integers can be written as:
2x-2, 2x, 2x+2, where x is integer
the sum of the first and third is three times the second even integer minus four
2x-2 + 2x+2 = 3*2x - 4
by solving we find:
x = 2
