Answer 2

Answer:

Sum of two numbers is 36. If 9 is subtracted from 8 times the first number, we get

Second number. To find the numbers complete the following.Let first number be x and the second number be y.

According to first condition.

x+y = 36… Eq (i)

According to second condition,

8x-9 =y

8x-y=9… Eq (ii)

For value of x→ Adding both the equations we get,

x+y+8x-y=36+9

9x=45

x=5

Substitute the value x of in Eq (i) to get the value of y

5+y=36

y=36-5

∴ y =31

2 required numbers are 5 and 31.
