Answer 2

Answer:

x=8

y=1

step by step explanation:

let the two number be x and y.

A.T.Q

• sum of two number is 9 (x+y=9)-----eqn (i)
• Difference of two number is 7(x-y=7)-----eqn (ii)

so,

eqn i : x+y=9

eqn ii : x-y=7

_______________

Adding : 2x= 16

=>x=16/2

=>x=8

substituting the value of x in eqn i

x+y=9

=>8+y=9

=>y=9-8

=>y=1

Hence, the value of x is 8 and the value of y is 1 .
