Question

For which values of a and b, will the following pair of linear equations have infinitely many solutions?x + 2y = 1 and (a – b)x + (a + b)y = a + b – 2

(A) a = 2 and b = 1
(B) a = 2 and b = 2
(C) a = 3 and b = 1
(D) a = 3 and b = 1​

Answer 1

Answer:

Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. So, the values (a,b)=(3,1) satisfies all the parts. Hence, required values of a and b are 3 and 1 respectively for which the given pair of linear equations has infinitely many solutions.
