Question

if x=a and y=b is the solution of linear eqvation x-y=2 and x+y=4 then the value of a and b are respectively ​

Answer 1

Answer:

(c) 3 and 1

Step-by-step explanation:

x = a and y = b

x - y = 2 ___(1) y = x - 2

x + y = 4 ___(2)

add equation (1) and (2) which gives,

2x = 6

x = 6/2 = 3

y = 3 - 2 = 1

Answer 2

Answer:

option no. C. 3 and 1

Step-by-step explanation:

x=a and y=b

x–y=2. 3–1=2

x+y=4 3+1=4

In this equation, 3 and 1 are used.

So, option no.C is the correct answer
