$|x| \leq a \Leftrightarrow -a \leq x \leq a$, for any positive number a

That should help.

Re: Basic Arithmetic, Basic Algebra, Basic Equations
Alice this inequality involves modulus..(Abs. Value)
your inequality is equivalent to two inequalities.......

4-3x<17 and -17<4-3x

solve them they are easy
