To solve an absolute value equation, first write two equations.

\

Equation 1: $\"\"$

\

$\"\"$

\

Equation 2: $\"\"$

\

$\"\"$

\

$\"\"$

\

Solve equation 1.

\

$\"\"$

\

According to Addition property of equality: if $\"\"$ , then $\"\"$ ; $\"\"$

\

$\"\"$ (Add 3 to each side)

\

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

\

$\"\"$ (Multiply each side by 4)

\

$\"\"$ (Cancel common terms)

\

$\"\"$ (Simplify)

\

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

\

$\"\"$

\

Solve equation 2.

\

$\"\"$

\

$\"\"$ (Add 3 to each side)

\

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

\

$\"\"$ (Multiply each side by 4)

\

$\"\"$ (Cancel common terms)

\

$\"\"$ (Simplify)

\

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

\

$\"\"$

\

The solution set is $\"\"$
