You can put this solution on YOUR website!
L = 3W-11
\n" ); document.write( "L * W = A
\n" ); document.write( "You can do this algebraically by substituting the value of L from the top equation into the bottom, but there's an easier way.
\n" ); document.write( "One of the factor sets of 42 is 7/6. You can tell right away that those are the correct numbers just by looking at the problem.
\n" ); document.write( "Prove it:
\n" ); document.write( "7 = 3(6) - 11
\n" ); document.write( "7 = 18-11
\n" ); document.write( "7 = 7
\n" ); document.write( "
\n" );
