You're right.
\n" ); document.write( ".
\n" ); document.write( "x = current age
\n" ); document.write( "x - 17 = how old he was 17 years ago
\n" ); document.write( "x-17 = 2/3x
\n" ); document.write( ".
\n" ); document.write( "multiply both sides by 3 to eliminate the fraction
\n" ); document.write( ".
\n" ); document.write( "3(x-17) = 2x
\n" ); document.write( ".
\n" ); document.write( "3x -51 = 2x
\n" ); document.write( ".
\n" ); document.write( "subtract 2x from both sides
\n" ); document.write( ".
\n" ); document.write( "x -51 = 0
\n" ); document.write( ".
\n" ); document.write( "add 51 to both sides
\n" ); document.write( ".
\n" ); document.write( "x = 51
\n" ); document.write( ".
\n" ); document.write( "check the answer
\n" ); document.write( ".
\n" ); document.write( "x-17 = 51-17 = 34
\n" ); document.write( "is 34 = 2/3*51?
\n" ); document.write( "yes
\n" ); document.write( ".
\n" ); document.write( "Answer: Arnold is 51 years old.
\n" ); document.write( ".
\n" ); document.write( "Done.
