X+Y=89 OR Y=89-X
\n" ); document.write( "4X+Y=155
\n" ); document.write( "4X+(89-X)=155
\n" ); document.write( "4X+89-X=155
\n" ); document.write( "3X=155-89
\n" ); document.write( "3X=66
\n" ); document.write( "X=66/3
\n" ); document.write( "X=22 ANSWER FOR THE SMALLER NUMBER.
\n" ); document.write( "22+Y=89
\n" ); document.write( "Y=89-22
\n" ); document.write( "Y=67 ANSWER FOR THE LARGER NUMBER.
\n" ); document.write( "PROOF:
\n" ); document.write( "4*22+67=155
\n" ); document.write( "88+67=155
\n" ); document.write( "155=155
