\

The equation is $\"\"$ .

\

Write two cases:

\

Case-1: $\"\"$ .

\

$\"\"$

\

Case-2: $\"\"$

\

$\"\"$ $\"\"$

\

Solve the equation for Case-1.

\

$\"\"$

\

Addition property of equality: if $\"\"$ , then $\"\"$ .

\

$\"\"$ (Add 8 on both sides)

\

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

\

$\"\"$ (Apply Additive identity property: $\"\"$ )

\

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

\

\

$\"\"$ (Divide both sides by 5)

\

$\"\"$ (Cancel common factors)

\

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