You can put this solution on YOUR website!
Start with the given system of equations:\r
\n" ); document.write( "\n" ); document.write( "\"system%284x-3y=1%2C-12x%2B9y=5%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%284x-3y%29=3%281%29\" Multiply the both sides of the first equation by 3.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"12x-9y=3\" Distribute and multiply.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we have the new system of equations:\r
\n" ); document.write( "\n" ); document.write( "\"system%2812x-9y=3%2C-12x%2B9y=5%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now add the equations together. You can do this by simply adding the two left sides and the two right sides separately like this:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%2812x-9y%29%2B%28-12x%2B9y%29=%283%29%2B%285%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%2812x%2B-12x%29%2B%28-9y%2B9y%29=3%2B5\" Group like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0x%2B0y=8\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0=8\"Simplify.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"0=8\" is NEVER true, this means that there are no solutions. So the system is inconsistent.
\n" ); document.write( "
\n" ); document.write( "
\n" );
