The system of equations are equations are $\"\"$ , $\"\"$

and $\"\"$ .

Eliminate one variable by using two pairs of equations.

Multiply the equation $\"\"$ by $\"\"$ and the equation $\"\"$ by $\"\"$ .

$\"\"$

Subtract the equation $\"\"$ from $\"\"$ .

$\"\"$

Therefore, the system is dependent.

There are infinitely many solutions.

Infinitely many solutions.
