Solve and graph the solution set.
\n" ); document.write( " $\"3x%3E=7x%2B20\"$
\n" ); document.write( " $\"-7x%2B3x%3E=-7x%2B7x%2B20\"$
\n" ); document.write( " $\"-4x%3E=20\"$
\n" ); document.write( " $\"-4x%2F-4%3C=20%2F-4\"$ Flip the inequality symbol if you multiply or divide by a negative number.
\n" ); document.write( " $\"x%3C=-5\"$
\n" ); document.write( "You will shade over the numbers less than -5 (to the left of the numberline) and put either a closed circle or a bracket ] over the -5 (depending on your book or teacher) because of the = part.
