Subtract the two equations,
\n" ); document.write( " $\"2x%2B3y-2x%2B5y=11-3\"$
\n" ); document.write( " $\"8y=8\"$
\n" ); document.write( " $\"y=1\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"2x%2B3=11\"$
\n" ); document.write( " $\"2x=8\"$
\n" ); document.write( " $\"x=4\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"M=%281%2B4%29%2F2\"$
\n" ); document.write( "Work that out for the answer.
