To determine how many solutions the system of equations has, we can analyze the two equations:

  1. \( 8x - 6y = 48 \)
  2. \( 8x + 6y = 48 \)

We can solve the system of equations by manipulation. Let's start by adding the two equations:

\[ (8x - 6y) + (8x + 6y) = 48 + 48 \]

This simplifies to:

\[ 16x = 96 \]

Now, we can solve for \(x\):

\[ x = \frac{96}{16} = 6 \]

Next, we can substitute \(x = 6\) back into one of the original equations to find \(y\). Let's use the first equation:

\[ 8(6) - 6y = 48 \]

Simplifying that gives:

\[ 48 - 6y = 48 \]

Subtracting 48 from both sides results in:

\[ -6y = 0 \]

Thus:

\[ y = 0 \]

So we have found a unique solution:

\[ (x, y) = (6, 0) \]

Now, we can check the second equation with these values:

\[ 8(6) + 6(0) = 48 \]

This simplifies to \(48 = 48\), confirming that the solution is valid.

Since we have one unique solution for \(x\) and \(y\), the system of equations has:

one solution.
