Elimination method:

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

$\"\"$ ----------(1)

$\"\"$ ----------(2)

To get two equations that contain opposite terms multiply the first equation by negative 3. $\"\"$

Add the equations to eliminate the q - variable and solve the equation.

$\"\"$

The resultant equation is $\"\"$ .

Divide each side by negative 10.

$\"\"$

The value of $\"\"$ substitute in either equation to find q.

First equation: $\"\"$ .

$\"\"$

Add 12 to each side.

$\"\"$

The solution is $\"\"$ .
