$\"\"$

\

Since the coefficients of the y-terms,-5 and +5,are additive inverses,

\

you can eliminate these terms by adding the equations. .

\

add the equations to eliminate variable y.

\

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

\

$\"\"$ (Divide each side by negative 7)

\

$\"\"$ (Cancel common terms) $\"\"$

\

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

\

$\"\"$ (Equation 1)

\

$\"\"$ (Multiply: $\"\"$ )

\

$\"\"$ (Subtract 3 from each side)

\

$\"\"$ (Commutative property: a+b=b+a)

\

$\"\"$ (Additive inverse property: $\"\"$ )

\

$\"\"$ (Additive indentity property: $\"\"$ )

$\"\"$ (Subtract: $\"\"$ )

\

$\"\"$ (Divide each side by negative 5)

\

$\"\"$ (Cancel common terms)

\

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