Question

# The pair of equations $$y = 0$$ and $$y = -7$$ has

A
one solution
B
two solution
C
infinitely many solution
D
no solution

Solution

## The correct option is B no solutionWe know that equation of the form $$y = a$$ is a line parallel to x-axis at distance 'a'from it . $$y = 0$$ is the equation of the x-axis and $$y = -7$$ is the equation of line parallel to the x-axis so, these two equations two parallel lines . therefore, there is no solution.hence (D) is correct answers.Mathematics
