Question

if x=a and x=b is the solution of the pair of equation x-y=2 and x+y=4 find the value of a and b​

Answer 1

Step-by-step explanation:

ohhh hello ladies vunaru

Answer 2

Step-by-step explanation:

x-y =2....eqn 1

x+y =4....eqn 2

then,

combining each other

x-y =2

+ x+y=4

2x = 6

x=6/2

x=3

hence the value of a and b is same

but I think that in question there is some mistake

x=a y=b
