\n" ); document.write( "D=Donald's speed; G=Gregory's speed=D-8mph
\n" ); document.write( "D+G=22 mph Substitute for G.
\n" ); document.write( "D+(D-8mph)=22mph Add 8 mph to each side.
\n" ); document.write( "2D=30 mph Divide each side by 2.
\n" ); document.write( "D=15 mph ANSWER 1: Donald's speed is 15 mph
\n" ); document.write( "G=D-8mph=15mph-8mph=7 mph ANSWER 2: Gregory' speed was 7 mph.
