\n" ); document.write( "Multiply the entire equation by 2
\n" ); document.write( " $\"2%28-3r%29+%2B+2%281%2F2%29+=+2%284%29\"$
\n" ); document.write( "-6r + 1 = 8
\n" ); document.write( "...
\n" ); document.write( "Isolate the r variable
\n" ); document.write( "-6r = 8 - 1
\n" ); document.write( "-6r = 7
\n" ); document.write( "...
\n" ); document.write( "Divide both sides by -6
\n" ); document.write( "r = $\"%287%2F-6%29+=+-%287%2F6%29\"$
