ax + 3y = (a - 3),
12x + ay = a has no solution.
A pair of linear equations represented by a x + b y + c = 0 and a x + b y + c = 0 has no solution, if a /a = b /b ≠ c /c .
⇒ a/12 = 3/a ≠ (a - 3)/a a/12 = 3/a
and 3/a ≠ (a - 3)/a
⇒ a = 36 and a - 6a ≠ 0
⇒ a = ± 6 and a = 0, 6
Therefore, the given system of equations has no solution for a = -6.

what is the value of b
that's the simple format of a quadratic eqn.
i used that just for representation.
b can be any no.
or constant you may say.
ok
thanx
sorry not quadratic but for linear.
and you're welcome!
