\n" ); document.write( " let x- dina's age
\n" ); document.write( " 2x- michelle's age; note that dina is half as old as michelle
\n" ); document.write( " x+3- juliet' age; note that dina is 3 years younger than juliet
\n" ); document.write( " we have defined their ages
\n" ); document.write( " the sum of their ages is 39:
\n" ); document.write( " x+2x+x+3=39
\n" ); document.write( " simplify then solve for x
\n" ); document.write( " x=9-age of dina
\n" ); document.write( " 2x=18-age of michelle
\n" ); document.write( " x+3=12-age of juliet
\n" ); document.write( " checking: 9+18+12=39
\n" ); document.write( "
