Without evaluating the system of equations, determine which of the following sentences is true about the system of equations listed below.
$\begin{array}{l} 7 x - 9 y = 4 \\ 9 y = 7 x - 6 \end{array}$

There will be infinitely many solutions because the coefficient of the x and y variable are the same.

There will be one solution because each equation represents a linear function, and there will be a point of intersection.

There is not enough given information to draw any conclusions.

There will be no solution because 7x – 9y cannot equal 4 and 6 at the same time.
