Answer
Neither are solutions
Work Step by Step
We are given that $5x-3y=9$.
In order to see whether each ordered pair is a solution of the given equation, we can plug in the ordered pair to the equation.
For (0,3): $5\times0-3\times3=-9\ne9$
So, (0,3) is not a solution.
For ($\frac{12}{5}$,-1): $5\times\frac{12}{5}-3\times-1=12+3=15\ne9$
So, ($\frac{12}{5}$,-1) is not a solution.
