Let $\"y\"$ = the number of years ago that
\n" ); document.write( "Marco's age was 1 and 1/2 times Michele's
\n" ); document.write( " $\"y\"$ years ago, Marco was $\"+30+-+y+\"$
\n" ); document.write( " $\"y\"$ years ago Michele was $\"+24+-+y+\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"+30+-+y+=+1.5%2A%2824+-+y%29+\"$
\n" ); document.write( " $\"+30+-+y+=+36+-+1.5y+\"$
\n" ); document.write( "Add $\"+1.5y+\"$ to both sides
\n" ); document.write( " $\"+30+%2B+.5y+=+36+\"$
\n" ); document.write( " $\"+.5y+=+6+\"$
\n" ); document.write( " $\"+y+=+12+\"$
\n" ); document.write( "The answer is 12 years ago
\n" ); document.write( "check:
\n" ); document.write( " $\"+30+-+12+-+18+\"$
\n" ); document.write( " $\"+24+-+12+=+12+\"$
\n" ); document.write( "18 is 1 and 1/2 times 12
\n" ); document.write( "OK
\n" ); document.write( " \n" ); document.write( "
