X+(2X+15)=90
\n" ); document.write( "3X+15=90
\n" ); document.write( "3X=90-15
\n" ); document.write( "3X=75
\n" ); document.write( "X=75/3
\n" ); document.write( "X=25 cm. ANS FOR THE SHORTER PIECE.
\n" ); document.write( "2*25+15=50+15=65 ANS. FOR THE LONGER PIECE.
\n" ); document.write( "PROOF:
\n" ); document.write( "25+65=90
