Question

for what value of a are the pair of equations 2x-y=a and 6x-3y=1 dependent​

Answer 1

Answer:

for consistent (dependent) pair of equations,

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

or, a1/a2 isn't equal to b1/b2. ....(ii)

Step-by-step explanation:

Let's check it.

a1/a2 = 2/6 = 1/3

b1/b2b = -1/-3 = 1/3

here, a1/a2 = b1/b2. so, we need to apply the first formula (i)th formula.

so, a1/a2 = b1/b2 = c1/c2 = 1/3

or, a/1 = 1/3 [since c1/c2 = 1/3]

or, a = 1/3 ,would be the answer
