Question

the sum of the two numbers is 20 and difference is 2. what is the ratio between the numbers​

Answer 1

Step-by-step explanation:

Let the no be x,y then (x+y)=20...(1)

6(x−y)=2.5..(2)

(1)+(2)⇒2x=22.5⇒

x=11.25

⇒

y=8.75

∴x:y=11.25:8.75

⇒

x:y=8:7

Answer 2

Answer:

9, 11

Step-by-step explanation:

x+y = 20 ------ i

x-y = 2 ------ii

add i + ii

2x = 22 => x = 11

put x= 11 in equation i

11+y = 20 => y = 9

Ans : Two numbers are 9, 11
