Dec 16, 2016

Solution: $x = 9 \mathmr{and} x = - 9$
$7 | \frac{x}{9} | = 7 \mathmr{and} | \frac{x}{9} | = 1 \mathmr{and} \frac{x}{9} = 1 \mathmr{and} x = 9$ And
$7 | \frac{x}{9} | = 7 \mathmr{and} | \frac{x}{9} | = 1 \mathmr{and} \frac{x}{9} = - 1 \mathmr{and} x = - 9$
Solution: $x = 9 \mathmr{and} x = - 9$ [Ans]
