$\"-12+%3C=+3x-7+%3C+-2\"$
\n" ); document.write( "I think the easiest way to solve these is to rewrite it as a compound inequality:
\n" ); document.write( " $\"-12+%3C=+3x-7\"$ and $\"3x-7+%3C+-2\"$
\n" ); document.write( "Now we solve each of these separately. Adding 7 to each side of both:
\n" ); document.write( " $\"-5+%3C=+3x\"$ and $\"3x+%3C+5\"$
\n" ); document.write( "Dividing both sides of each by 3 we get:
\n" ); document.write( " $\"%28-5%29%2F3+%3C=+x\"$ and $\"x+%3C+5%2F3\"$
\n" ); document.write( "which is our answer. Or, if we want to write it in the original form:
\n" ); document.write( " $\"%28-5%29%2F3+%3C=+x+%3C+5%2F3\"$ \r
