Question

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

Answer 1

Answer:

The required values are a = 3 and b = 1. for a system of linear equations to have infinitely many solutions, the coefficients of the unknown variables (x and y) and the constant terms must be in proportion. Thus, the required values are a = 3 and b = 1.

Answer 2

Answer:

the answer is y and 2 a+b=2
