2a + 3e = 58.75
\n" ); document.write( "4a + 5e = 102.50
\n" ); document.write( "solve first equation for a
\n" ); document.write( "2a = 58.75 - 3e
\n" ); document.write( "a = (58.75 - 3e) / 2
\n" ); document.write( "now substitute for a in the second equation
\n" ); document.write( "4(58.75 - 3e) / 2 +5e = 102.50
\n" ); document.write( "2(58.75 - 3e) + 5e = 102.50
\n" ); document.write( "117.50 - 6e + 5e = 102.50
\n" ); document.write( "-e = -15
\n" ); document.write( "e = 15.00
\n" ); document.write( "now substitute for e in first equation
\n" ); document.write( "2a + 45.00 = 58.75
\n" ); document.write( "2a = 13.75
\n" ); document.write( "a = 6.875
\n" ); document.write( "therefore
\n" ); document.write( "e = $15.00 and a = $6.875
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
