P=7Y+2XY-6X
\n" ); document.write( "Q=5-7Y THEN:
\n" ); document.write( "3P=3(7Y+2XY-6X)=21Y+6XY-18X
\n" ); document.write( "4Q=4(5-7Y)=20-28Y
\n" ); document.write( "NOW SUBTRACT 4Q(20-28Y) FROM 3P(21Y+6XY-18X)
\n" ); document.write( "21Y+6XY-18X-(20-28Y)
\n" ); document.write( "21Y+6XY-18X-20+28Y
\n" ); document.write( "49Y+6XY-18X-20 ANSWER.
