Question 384715
x = one of the integers
y = the other


x = 2*y
x + y <= 12


substitute for x in the second equation to get:


2*y + y <= 12


combine like terms to get:


3*y <= 12


divide both sides by 3 to get:


y <= 4


the greatest that y can be is 4.


if y is equal to 4, then x = 2*y means that x = 8


the greatest that x can be is 8.


when x = 8 and y = 4, then:


8 = 2*4 = ok
4 + 8 = 12 = ok
