Question

The pair of equations x = a and y = b has solution ________.

Answer 1

The equation x = a is the line parallel to y-axis and y = b is the line parallel to x-axis.

​Therefore, both the lines intersect each other.

The point of intersection is x = a and y = b i.e. (a, b).

Hence, the pair of equations x = a and y = b has solution (a, b).
