Lucas is 9 years older than three times his son’s age. In 14 years, the age of Lucas will be 6 years more than twice his son’s age. Find their present ages.
\n" ); document.write( "PARTIAL SOLUTION
\n" ); document.write( "x= son's age. So lucas age= 3x+9
\n" ); document.write( "After 14 years, son age= x +14, lucas age= 2(x+14)+6
\n" ); document.write( "Not sure how to move ahead
\n" ); document.write( "

After 14 years, the son will be x + 14 -------- You're correct up to here
\n" );
document.write( "After 14 years, Lucas' age will be: 3x + 9 + 14, or 3x + 23
\n" );
document.write( "Since at that time (14 years hence), Lucas' age will be 6 years more than twice his son's age (the son's age in 14 years, I presume), then we can say that:
\n" );
document.write( "3x + 23 = 2(x + 14) + 6
\n" );
document.write( "3x + 23 = 2x + 28 + 6
\n" );
document.write( "3x + 23 = 2x + 34
\n" );
document.write( "3x - 2x = 34 - 23
\n" );
document.write( "x, or son's current age: 
\n" );
document.write( "Lucas' current age: 3(11) + 9, or 33 + 9, or  \n" );
document.write( "

\n" );
