\"\"

\

The equations are

\

\"\"                      (Equation 1)

\

\"\"                             (Equation 2)

\

Since \"\"

\

Rewrite the second equation for x.

\

\"\"

\

\"\"

\

Apply addition property of equality: Add 2y to each side.

\

\"\"

\

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

\

\"\"                  (Apply additive identity property: \"\")\"\"

\

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

\

\"\"                          (Equation 1)

\

\"\"          (Replace \"\")

\

Distribute terms using distributive property: \"\".

\

\"\"

\

\"\"        (Multiply: \"\")

\

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

\

Apply addition property of equality: Add 44 to each side.

\

\"\"

\

Apply commutative property of addition: \"\".

\

\"\"

\

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

\

\"\"                (Apply additive identity property: \"\")

\

\"\"                            (Add: \"\")\"\"

\

Apply division property of equality: Divide each side by 15.

\

\"\"

\

\"\"                                (Cancel common terms)                    

\

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

\

Now  \"\"

\

\"\"                 (Replace y by 2)

\

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

\

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

\

The solution is \"\"\"\"

\

The solution is \"\".
