Question

What value of p and q for which the following system of equation has infinitly many solution
2x-3y=7
(a+b)x-(a+b-3)=4a+b​

Answer 1

Answer:

a1/a2=b1/b2=c1/c2

2/(a+b)= -3/(a+b-3)=7/4a+b

2×(a+b-3)= -3×(a +b)

2a+2b-6= -3a -3b

5a+5b=6--1eq

2/(a+b)= 7/4a+b

8a+2b=7a+7b

a=5b ----put in 1

5×5b+5b=6

30b=6

b=5

a=5×5

a=25
