Please help me solve this question. I need to solve the system for x and y. I need to show an answer as an ordered pair, (x,y).
\n" ); document.write( "x + y = -9
\n" ); document.write( "x + y = -2
\n" ); document.write( "------
\n" ); document.write( "If you assume there is such an (x,y) pair,
\n" ); document.write( "and you subtract one equation from the other
\n" ); document.write( "you would get the following:
\n" ); document.write( "0 = 7
\n" ); document.write( "---
\n" ); document.write( "That is a contradiction.
\n" ); document.write( "Why did it happen?
\n" ); document.write( "---
\n" ); document.write( "Because you assumed there was an (x,y) pair.
\n" ); document.write( "---
\n" ); document.write( "Conclusion:
\n" ); document.write( "There is no such x/y pair.
\n" ); document.write( "There is no solution for the system.
\n" ); document.write( "The system is said to be \"inconsistent\".
