evaluate
\n" ); document.write( "28z-15=15
\n" ); document.write( "28z-15+15=15+15
\n" ); document.write( "28z=30
\n" ); document.write( " $\"28z%2F28=30%2F28\"$
\n" ); document.write( " $\"z=30%2F28\"$
\n" ); document.write( " $\"z=%282%2A15%29%2F%282%2A14%29\"$
\n" ); document.write( " $\"highlight%28x=15%2F14%29\"$
\n" ); document.write( "Check by substituting 15/14 in for x in the original equation and see if both sides =.
