The pair of linear equations 3x + 4y = 12 and y =4 has

a. no common solution b. infinetly many solutions c. unique solution d. none of these

**Given,** pair of equation are:

3*x* + 4*y* = 12 and *y* = 4

They can be rewritten as:

3*x *+ 4*y* – 12 = 0 ... (1)

and *y* = 4

Put *y* = 4 in (1), we get

3*x *+ 4 (4) – 12 = 0

⇒ 3*x *– 4 = 0

So, the given system of equation will have unique solution for and *y* = 4.
