Answer:

25 and 15

Step-by-step explanation:

let the 2 numbers be x and y , x > y , then

x + y = 40 → (1)

x - y = 10 → (2)

add the 2 equations term by term to eliminate y

2x + 0 = 50

2x = 50 ( divide both sides by 2 )

x = 25

substitute x = 25 into (1)

25 + y = 40 ( subtract 25 from both sides )

y = 15

the 2 numbers are 25 and 15
