Question

Sum of two numbers is 25 and their difference is 9. What are the numbers​

Answer 1

Answer:

• 7 and 18

Step-by-step explanation:

Let's say the numbers are x and y

Then,

• x + y = 25. . . .(i)
• x - y = 9 . . . . (ii)

By elimination method,

x + y = 25

x - y = 9

=> 2y = 14

=> y = 7

Substituting y in eq.(i) :-

=> x + y = 25

=> x + 7 = 25

=> x = 18

The two numbers are 7 & 18
