Answer:
7 and 13
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x = y + 6 → (1)
(x + y) = y – 2 ( multiply both sides by 4 to clear the fraction )
x + y = 4y – 8 ( subtract 4y from both sides )
x – 3y = – 8 → (2)
Substitute x = y + 6 into (2)
y + 6 – 3y = – 8
– 2y + 6 = – 8 ( subtract 6 from both sides )
– 2y = – 14 ( divide both sides by – 2 )
y = 7
Substitute y = 7 into (1)
x = 7 + 6 = 13
The 2 numbers are 7 and 13
