Elimination method:

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

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

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

In the above system the coefficients of y - variable are same. $\"\"$

Subtract the equations to eliminate the y - variable and solve the equation.

$\"\"$

The resultant equation is $\"\"$ .

$\"\"$

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

Second equation: $\"\"$ .

$\"\"$

Add 3 to each side.

$\"\"$

Divide each side by 3.

$\"\"$

The solution is $\"\"$ .
