Question

If x = a , y = b is the solution of the systems of equations x - y = 2 & x + y = 4, then the values

of 'a' and 'b' are, respectively

(A) 3 & 1 (B) 3 & 5 (C) 5 & 3 (D) - 1​

Answer 1

Answer:

option A is the answer for the given problem

Answer 2

Answer:

option a 3&1

Step-by-step explanation:

as x=a,y=b

substituting in the given equation we get,

a-b=2----------1

a+b=4---------2

solving by elimination method we get,i.e.adding 1&2

2a=6

a=3

substituting value of a in 2 we get

3+b=4

b=1
