Add $\"R%5B1%5D\"$ and $\"R%5B2%5D\"$ to eliminate $\"a\"$ ,
\n" ); document.write( " $\"2a%2B3b-5c-2a-2b-c=-5-14\"$
\n" ); document.write( " $\"R%5B4%5D\"$ : $\"b-6c=-19\"$
\n" ); document.write( "Multiply $\"R%5B1%5D\"$ by $\"R%5B2%5D\"$ and subtract from $\"R%5B3%5D\"$ to eliminate $\"a\"$ ,
\n" ); document.write( " $\"4a-4b%2B4c-4a-6b%2B10c=-4%2B10\"$
\n" ); document.write( " $\"R%5B5%5D\"$ : $\"-10b%2B14c=6\"$
\n" ); document.write( "Multiply $\"R%5B4%5D\"$ by 10 and add to $\"R%5B5%5D\"$ to eliminate $\"b\"$ .
\n" ); document.write( " $\"10b-60c-10b%2B14c=-190%2B6\"$
\n" ); document.write( " $\"-46c=-184\"$
\n" ); document.write( " $\"c=%28-184%29%2F%28-46%29\"$
\n" ); document.write( "Solve for $\"c\"$ then work backwards to solve for $\"b\"$ and then $\"a\"$ .
\n" ); document.write( " \n" ); document.write( "

\n" );
