\"5%282x%2B1%29%2B4%3C8x%2B6\"
\n" ); document.write( ".
\n" ); document.write( "Operate on this just as you would on an equation. For the first step, you can multiply
\n" ); document.write( "out the left side to get:
\n" ); document.write( ".
\n" ); document.write( "\"10x+%2B+5+%2B+4+%3C+8x+%2B+6\"
\n" ); document.write( ".
\n" ); document.write( "Combine the +5 and the +4 on the left side. The inequality becomes:
\n" ); document.write( ".
\n" ); document.write( "\"10x+%2B+9+%3C+8x+%2B+6\"
\n" ); document.write( ".
\n" ); document.write( "Eliminate the +9 on the left side by adding -9 to both sides:
\n" ); document.write( ".
\n" ); document.write( "\"10x+%3C+8x+%2B6+-9\"
\n" ); document.write( ".
\n" ); document.write( "And add the +6 and -9 on the right side:
\n" ); document.write( ".
\n" ); document.write( "\"10x+%3C+8x+-+3\"
\n" ); document.write( ".
\n" ); document.write( "Get rid of the 8x on the right side by adding -8x to both sides. The inequality simplifies to:
\n" ); document.write( ".
\n" ); document.write( "\"2x+%3C+-3\"
\n" ); document.write( ".
\n" ); document.write( "Dividing both sides by 2 results in:
\n" ); document.write( ".
\n" ); document.write( "\"x+%3C+%28-3%2F2%29\"
\n" ); document.write( ".
\n" ); document.write( "This tells you that x can be anywhere on the number line below the value \"-3%2F2\".
\n" ); document.write( "But x cannot equal \"%28-3%2F2%29\"and it cannot be any value to the right of \"%28-3%2F2%29\"
\n" ); document.write( "on the number line.
\n" ); document.write( ".
\n" ); document.write( "It doesn't happen in this problem, but remember this rule: if you multiply or divide an
\n" ); document.write( "inequality by a negative number you must change the inequality sign to the opposite
\n" ); document.write( "direction.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you see how to work with inequalities.
