Elimination method:

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

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

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

To get two equations that contain opposite terms multiply the first equation by 4. $\"\"$

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

$\"\"$

The resultant equation is $\"\"$ .

Divide each side by 23.

$\"\"$

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

First equation: $\"\"$ .

$\"\"$

Subtract 20 from each side.

$\"\"$

The solution is $\"\"$ .
