Question

for the pair of equations lambda x + 3y = -7

2x + 6y = 14

to have infinitely many solutions, the value of lambda should be ???​

Answer 1

Answer:

lamda =1

Step-by-step explanation:

If the equation have infinitely many solutions then

(a1/a2) = (b1/b2) = (c1/c2)

=>lamda/2=3/6

=>lamda= 3×2/6

=>lamda=1
