Answer:
28 and 19
Explanation:
let the 2 numbers be x and y, x > y, then
x + y = 47 → (1) ← sum of numbers
x - y = 9 → (2) ← difference of numbers
Adding the 2 equations to eliminate y
2x = 56 ( divide both sides by 2 )
x = 28
substitute x = 28 into (1) and solve for y
28 + y = 47 ( subtract 28 from both sides )
y = 47 - 28 = 19
The 2 numbers are 28 and 19
