Answer:
3y -6
Explanation:
x = 1st integer
x+2 = next consecutive even integer
x+4 = 3rd consecutive even integer
Largest is y
x+4 = y
We want x in terms of y
x = y-4
y-4 = 1st integer
y-4+2 = y-2 = next consecutive even integer
y-4+4 = y = 3rd consecutive even integer
Sum them together
y-4 + y-2 +y
Combine like terms
3y -6
