Question

If x=a , y=b is the solution of equation x-y=2 and x+y=4 then the values of ‘a’and ‘b’are

Answer 1

Answer:

a= 3 ,b = 1

Step-by-step explanation:

Given x = a , y = b ,

and

x-y = 2 ---(1)

x+y = 4 ---(2)

/* Add (1) and (2) , we get

=> 2x = 6

=> x = 6/2 = 3

/* Put x = 3 ,in equation (1) , we get

=> 3-y = 2

=> -y = 2-3

=> -y = -1

=> y = 1

Therefore,

a = x = 3 ,

b = y = 1
