\

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

\

Equation 1: $\"\"$

\

Equation 2: $\"\"$ .

\

Observe the coefficient of each term, the coefficient of x - term is one in the second equation, so the best method is substitution method to solve the system of equations.

\

Substitution method:

\

Solve the second equation, $\"\"$ for x since the coefficient is 1.

\

Add 3y to each side

\

\

The value of $\"\"$ substitute in the first equation, $\"\"$ to find y.

\

Subtract 16 from each side.

\

$\"\"$

\

$\"\"$

\

Divide each side by 12.

\

The value of $\"\"$ substitute in the either equation to find x.

\

Equation 1: $\"\"$

\

$\"\"$

\

$\"\"$

\

Add 12 to each side.
