9. x+5y=0 25y=-5x x=square y 25y=-5(square ) 25y=square y The statement is true There are square solutions.

To solve the system of equations, we can start by solving the first equation for x:<br /><br />$x + 5y = 0$<br />$x = -5y$<br /><br />Now we can substitute this expression for x into the second equation:<br /><br />$25y = -5(-5y)$<br />$25y = 25y$<br /><br />This equation is always true, which means that the system of equations has infinitely many solutions. Therefore, the statement is true and there are infinitely many solutions.
