$\"system%286x%2B8y=22%2C+-5x%2By=20%29\"$
\n" ); document.write( "from the second equation $\"y=5x%2B20\"$ substitute into the first equation
\n" ); document.write( " $\"6x%2B8%285x%2B20%29=22\"$
\n" ); document.write( " $\"6x%2B40x%2B160=22\"$
\n" ); document.write( " $\"46x=22-160\"$
\n" ); document.write( " $\"46x=-138\"$
\n" ); document.write( " $\"x=-138%2F46\"$
\n" ); document.write( " $\"x=-3\"$
