$\displaystyle \frac {x}{8} - 1 < -2$

$\displaystyle \frac {x}{8} < -1$

both sides by 8.**Multiply**

$\displaystyle x < -8$

the question was not the answer I've already givin. the question was why

doesn't the inequality reverse , knowing the rule is when you multiply or devide by a negative number you reverse the equality. - Feb 3rd 2009, 01:42 PMtopher0805
