\

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

\

Since the coefficient of the y - terms in two equations, $\"\"$ are additive inverse, eliminate these terms by adding the equations.

\

Write the equations in column form and add to eliminate variable y.

\

$\"\"$ . $\"\"$

\

The resultant equation is $\"\"$ and solve it for x.

\

$\"\"$

\

$\"\"$

\

Multiply each side by $\"\"$ .

\

$\"\"$

\

Cancel common terms.

\

$\"\"$ . $\"\"$

\

Substitute the value of $\"\"$ in equation 1: $\"\"$ and solve for y.

\

$\"\"$

\

$\"\"$

\

Subtract 1 from each side.

\

$\"\"$

\

$\"\"$

\

Multiply each side by $\"\"$ .

\

$\"\"$

\

Cancel common terms.

$\"\"$

\

$\"\"$ . $\"\"$

\

The solution is $\"\"$ .
