S-son's age
\n" ); document.write( "Y-your age
\n" ); document.write( "G-grandson's age
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "1.\"S=Y-24\"\"son is 24 years younger than I\"
\n" ); document.write( "2.\"S=35%2BG\"\"son is 35 years older than my grandson\"
\n" ); document.write( "3.\"G%2BS%2BY=100\"\"together our total ages add up to 100\"
\n" ); document.write( "From 1,
\n" ); document.write( "\"Y=S%2B24\"
\n" ); document.write( "From 2.
\n" ); document.write( "\"G=S-35\"
\n" ); document.write( "Substitute both of these into 3,
\n" ); document.write( "\"%28S-35%29%2BS%2B%28S%2B24%29=100\"
\n" ); document.write( "\"3S=111\"
\n" ); document.write( "\"S=111%2F3\"
\n" ); document.write( "Solve for \"S\" then use the equations to solve for \"G\" and \"Y\".
