Question

For what value of ‘a’ and ‘b’ will the equation x + 2y =1 and
(a-b)x + (a+b)y = a+b -2 have an infinite number of solutions
Class 10

Answer 1

Answer:

a=3 and b=1

Step-by-step explanation:

we know that to get an infinite number of solutions

we have a1/a2 = b1/b2 = c1/c2.......(1)

here by question,

a1= 1 , b1=2 and c1=1

a2 = a-b, b2 = a+b and c2 = a+b-2

on keeping these values in (1) we get a=3 and b=1
