Question

1. For what values of a and b does the
following pair of equations have an infinite
numbers of solutions. 2x+3y=7, a(x+y)-
b(x-y)=3a+b-2 (DELHI 2008 C)​

Answer 1

Step-by-step explanation:

a = 5 and b = 1 is the value of the pair of linear equations \bold{2x + 3y = 7}and \bold{a(x + y) -b(x-y) = 3a +b -2}

Given:

2x + 3y = 7

a(x+y) -b(x-y) = 3a +b -2
