Question

For which values of a and b does the following pair of linear equations have an
infinite number of solutions?
2x+3y=7
(a - b).x + (a + b) y = 3a +b - 2
​

Answer 1

Explanation:

Summary: (i) The values of a and b for which the equations 2x + 3y = 7 and (a - b) x + (a + b) y = 3a + b - 2 will have infinitely many solutions will be a = 5 and b = 1.
