You can put this solution on YOUR website!
Let's say that z = -2x+5y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So this would mean that equation 1 would go from -2x+5y = 7 to z = 7 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and equation 2 would go from -2x+5y = 12 to z = 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "But z is only ONE number. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So z can't be both 7 and 12 at the same time. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So there are no numbers z which satisfy the system, which means by extension, there are no numbers x and y which satisfy the system \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: So there are NO solutions. This means that the system is inconsistent.\r
