\n" ); document.write( "P = 2x + 2(x - 3)
\n" ); document.write( "P = 54
\n" ); document.write( "54 = 2x + 2(x - 3)
\n" ); document.write( "54 = 2x + 2x - 6
\n" ); document.write( "4x = 54 + 6
\n" ); document.write( "4x = 60
\n" ); document.write( "x = 15
\n" ); document.write( "The sides are 15 and 12
\n" ); document.write( "check:
\n" ); document.write( "P = 2*15 + 2(15 - 3)
\n" ); document.write( "P = 30 + 2 * 12
\n" ); document.write( "P = 30 + 24
\n" ); document.write( "P = 54
\n" ); document.write( "OK
