If x=a,y=b is the solution of the equations x−y=2 and x+y=4, then the values of a and b are, respectively:
Question 11 If x = a and y = b is the solution of the equations x – y = 2 and x + y = 4, then the values of a and b are respectively: (A) 3 and 5 (B) 5 and 3 (C) 3 and 1 (D) –1 and –3
If the pair of linear equations 3x-5y=11 and (5a+b)x-(7a-b)y=4(3a-2b)+1 have infinitely many solutions then find the value of a and b
