$\"system%285u-v=0%2C+3u%2B3v=-18%29\"$
\n" ); document.write( "Myltiply the first equation by 3
\n" ); document.write( " $\"system%2815u-3v=0%2C+3u%2B3v=-18%29\"$
\n" ); document.write( "Add the first equation to the second
\n" ); document.write( " $\"18u=-18\"$ divide by 18
\n" ); document.write( " $\"u=-1\"$
\n" ); document.write( "Substitute $\"u=-1\"$ into the first equation
\n" ); document.write( " $\"5%2A%28-1%29-v=0\"$
\n" ); document.write( " $\"-5-v=0\"$
\n" ); document.write( " $\"-v=5\"$
\n" ); document.write( " $\"v=-5\"$
\n" ); document.write( "So
\n" ); document.write( " $\"system%28u=-1%2C+v=-5%29\"$ the solution of the system
\n" ); document.write( "Answer: (-1, -5) \n" ); document.write( "
