\

Elimination method:

\

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

\

In the system of the equations, coefficients of $\"\"$ -variable are same.

\

Add the equations to eliminate the $\"\"$ -variable and solve the equation.

\

$\"\"$

\

$\"\"$ (The resultant equation)

\

$\"\"$ (Divide each side by $\"\"$ )

\

$\"\"$ (Cancel common terms)

\

$\"\"$

\

Find $\"\"$ .

\

$\"\"$ (First equation)

\

$\"\"$ (Substitute $\"\"$ in the equation)

\

$\"\"$ (Multiply)

\

$\"\"$ (Subtract $\"\"$ from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ (Divide each side by $\"\"$ )

\

$\"\"$ (Cancel common terms)

\

Therefore, the solution is $\"\"$ and $\"\"$ .
