Question 989093
{{{36-9/5<abs(-2x+18/5)}}}, isolates the absolute value.


{{{(36*5-9)/5<abs(-2x+18/5)}}}


{{{171/5<abs(-2x+18/5)}}}


Solve each of these, according to the expression being either non-negative and negative:
(Better way to explain is, solve for two conditions.  -2x+18/5 may be greater or equal to zero; and -2x+18/5 may be less than zero.


{{{system(-2x+18/5>171/5,2x-18/5>171/5)}}}
Solve each of these separately.
