Elimination method:

The system of equations are

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

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

In the above system the coefficients of v - variable are opposite. $\"\"$

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

$\"\"$

The resultant equation is $\"\"$ .

Divide each side by 2.

$\"\"$

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

Second equation: $\"\"$ .

$\"\"$

Subtract 4 from each side.

$\"\"$

The solution is $\"\"$ .
