L = 3W-4
\n" ); document.write( "and
\n" ); document.write( "2L+2W = 40 Substitute for L:
\n" ); document.write( "2(3W-4)+2W = 40
\n" ); document.write( "6W-8+2W = 40
\n" ); document.write( "8W = 48
\n" ); document.write( "W = 6 This is the width, and the Length:
\n" ); document.write( "L = 3(6)-4 = 14
\n" ); document.write( "```````````````````````````````````````````````
\n" ); document.write( "Check:
\n" ); document.write( "2(6)+2(14)= 40
\n" ); document.write( "12+28 = 40 Correct.
