Question

find the value of a and b
when this equation is infinitely many solution​

Answer 1

Answer:

Step-by-step explanation:

2x+3y=7

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

a1/a2=2/a-b

b1/b2=3/a+b

a1/a2=b1/b2=c1/c2(for infinitely many solns)

2/a-b=3/a+b

2a+2b=3a-3b(Cross multiplied)

2a-3a= -3b-2b

-a= -5b

a=5b

Substitute value of a in a1/a2=c1/c2

You will get value of a & b.
