20

Step-by-step explanation:

15 - 5= 20

therefore 20 is the answer

Answer 2

Answer:

let the two numbers be x and y

According to given question;

x + y = 15.........(i)

x - y =5.........(ii)

put x = 15 -y [from eq(i)] in eq(ii)

15 - y - y = 5

-2y = -10

y = 5

x = 15 - y

x = 15-5 = 10

therefore,x=10 and y = 5........
