The equation is $\"\"$ .

Solve the eqation.

Case(i):

$\"\"$ (Original equation)

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

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

Case(ii):

$\"\"$ (Original equation)

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

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

Therefore the value of $\"\"$ is $\"\"$ .
