Turn each statement into an equation using the fewest possible unknowns.
\n" ); document.write( ".
\n" ); document.write( "L = length of the rectangle
\n" ); document.write( ".
\n" ); document.write( "Length is twice the width plus 5.
\n" ); document.write( "L = 2W + 5
\n" ); document.write( ".
\n" ); document.write( "P = perimeter of a rectangle.
\n" ); document.write( "P = 2L + 2W = 2(L + W)
\n" ); document.write( "P = 34 (given)
\n" ); document.write( ".
\n" ); document.write( "Substituting what we know...
\n" ); document.write( "34 = 2(L + W)
\n" ); document.write( ".
\n" ); document.write( "Divide both sides by 2...
\n" ); document.write( "17 = L + W
\n" ); document.write( ".
\n" ); document.write( "Substituting L = 2W+5...
\n" ); document.write( "17 = 2W + 5 + W
\n" ); document.write( ".
\n" ); document.write( "Collecting terms and subtracting 5 from both sides
\n" ); document.write( "12 = 3W
\n" ); document.write( "so
\n" ); document.write( "3W = 12
\n" ); document.write( ".
\n" ); document.write( "Dividing both sides by 3
\n" ); document.write( "W = 4
\n" ); document.write( ".
\n" ); document.write( "L = 2W+5
\n" ); document.write( "L = 2(4)+5
\n" ); document.write( "L = 8+5
\n" ); document.write( "L = 13
\n" ); document.write( ".
\n" ); document.write( "Checking the perimeter
\n" ); document.write( "P = 2(L+W) = 2(13+4) = 2(17) = 34
\n" ); document.write( ".
\n" ); document.write( "Checks.
\n" ); document.write( "
\n" );
