1. $\"A%2BB=1000\"$
\n" ); document.write( "2. $\"4A%2B6.5B=5000\"$
\n" ); document.write( "Multiply eq. 1 by 4 and subtract from eq. 2,
\n" ); document.write( " $\"4A%2B6.5B-4A-5B=5000-4000\"$
\n" ); document.write( " $\"2.5B=1000\"$
\n" ); document.write( "Now solve for B.
\n" ); document.write( "Then use either equation to solve for A.\r
