Question

If x = a and y = b is the solution of pair of linear equation x-y=2 and x + y= 4 then, what will be value of a and b

Answer 1

Answer:

a = 3, b = 1

Step-by-step explanation:

x=a , y=b

so, x+y = a+b = 4

and, x-y = a-b = 2

then, BTP,

=> (a+b)+(a-b) = 4+2

=> 2a = 6

=> a = 3 , => b = 4-a

=> b = 4-3

=> b = 1
