Question

If x=a , y=b is the soluyionof the equation x-y=2 & x+y=4 , then the values of a & b are , repectively :(a)3 and 5(b)5 and 3(c)3 and 1(d)-1 and -3

Answer 1

 If x=a and y=b is the solution of the equations x-y=2 and x+y =4 then the value of a and b are, respectively. ( A ) 3 and 5 ( B ) 3 and 1 ( C ) 5 and 3 ( D ) -1 and -3.

Answer 2

solving both equations simultaneously, we get,
2x=6
x=3
thus a=3
substituting value of x in (x-y=2)
3-y=2
y=1
thus b=1

hope this helps!
