Printing press model A can print 70 books per day and model B can print 55 per day.
\n" ); document.write( " If there are 14 total presses and together they print 905 books per day, how many books does each model print per day?
\n" ); document.write( ":
\n" ); document.write( "No. of presses equation
\n" ); document.write( "A + B = 14
\n" ); document.write( "B = (14-A); use this form for substitution
\n" ); document.write( ":
\n" ); document.write( "Output equation
\n" ); document.write( "70A + 55B = 905
\n" ); document.write( "Replace B with (14-A)
\n" ); document.write( "70A + 55(14-A) = 905
\n" ); document.write( "70A + 770 - 55A = 905
\n" ); document.write( "70A - 55A = 905 - 770
\n" ); document.write( "15A = 135
\n" ); document.write( "A = 135/15
\n" ); document.write( "A = 9 presses
\n" ); document.write( ":
\n" ); document.write( "You can find the number of B presses, Check the solutions in the output equation \n" ); document.write( "
\n" );
