\

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

\

\"\"    Equation (1)

\

\"\"    Equation (2)

\

Solve the second equation for x.

\

Apply subtraction property of equality: Subtract 4y from each side.

\

 

\

\"\"

\

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

\

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

\

\"\"

\

Apply division property of equality: Divide each side by 8.

\

\"\"

\

\"\" (\"\")

\

\"\"                     (Cancel common terms)

\

\"\"

\

Substitute \"\" in equation (1).

\

\"\"

\

\"\"  (\"\")

\

\"\"  (Cancel common terms)

\

Distribute terms using distributive property: a( b \"\" c ) = ab \"\" ac.

\

\"\"

\

\"\"     (Multiply: \"\")

\

\"\"           (Subtract: \"\")

\

\"\"\"\"(Subtract 33 from each side)

\

Rearrange the terms using commutative property of addition: a + b = b + a.

\

\"\"

\

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

\

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

\

\"\"                 (Subtract: \"\")

\

\"\"

\

\"\"            (Divide each side by negative 10)

\

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

\

Now, find the x value by substitute  \"\" in \"\".

\

\"\"

\

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

\

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

\

The system of solution is \"\".
