$\"6a=6-b\"$ ...........1\r
\n" ); document.write( "\n" ); document.write( " $\"6a=3-b\"$ ..........2
\n" ); document.write( "___________________________\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"6a=6-b\"$ ...........1...solve for $\"b\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"b=6-6a\"$ ..........substitute in 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"6a=3-%286-6a%29\"$ ..........2.solve for $\"a\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"6a=3-6%2B6a\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"6a-6a=-3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0=-3\"$ ........Since this expression is not true, we have an $\"inconsistency\"$ . So there are no solutions. The simple reason is the 2 equations represent $\"2\"$ $\"+parallel\"$ lines that will never intersect. Since no intersections occur, no solutions exist.\r
