4x-12y=5----------(1)
\n" ); document.write( "-x+3y=-1-----------(2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "consider equation (2)\r
\n" ); document.write( "\n" ); document.write( "-x + 3y = -1\r
\n" ); document.write( "\n" ); document.write( "3y = -1+x\r
\n" ); document.write( "\n" ); document.write( "y = -1+x/3 (by transposing)\r
\n" ); document.write( "\n" ); document.write( "plugging the value of y in equation (1), we have\r
\n" ); document.write( "\n" ); document.write( "4x-12(-1+x/3)=5\r
\n" ); document.write( "\n" ); document.write( "4x + 12/3 -12x/3 = 5\r
\n" ); document.write( "\n" ); document.write( "4x + 4 - 4x= 5\r
\n" ); document.write( "\n" ); document.write( "Since we have +4x and -4x in the above equation, they get cancelled \r
\n" ); document.write( "\n" ); document.write( "hence there is no solution for the above equation.\r
\n" ); document.write( "\n" ); document.write( " Hence the system is inconsistent \r
