Question

Fine p and q for which (p-1) x+3y=2, 6x+(1-2q)y=6 has infinistennimber of solutions ​

Answer 1

Step-by-step explanation:

(p-1) x+3y=2 -----------eq1

6x+(1-2q)y=6 ------------eq2

for infinite number of solution

multiply eq1 with 3

3* ((p-1) x+3y=2)

=> 3(p-1) x+ 9y = 6 ---------eq3

compare eq 2 and eq3

so

3(p-1)= 6 and (1-2q)= 9

=> 3p = 3 and 2q = -8

=> p= 1 and q= -4
