\

Rewrite the first equation

\

$\"\"$ $\"\"$

\

Since the coefficients of the x-terms, +6and +6, are same,

\

you can eliminate these terms by subtracting the equations. .

\

Subtract the equations to eliminate variable x.

\

$\"\"$ (Write the equations in column form and subtract)

\

$\"\"$

\

Apply division property of equality: Divide each side by negative 7.

$\"\"$ (Divide: $\"\"$ ) $\"\"$

\

Now Substitute $\"\"$ for y in either equation to find the value of x.
