Solution

The correct option is C
(x = 2,y = -1)

The solution of a linear equation must be able to satisfy the equation.
Among the given options, point (2,-1) satisfies the given equation.
Putting the value of x and y in the equation we get:
3(2) + 4(-1) = 2.

Thus, (x = 2, y = -1) is the solution.
