\n" ); document.write( "-6(1+7k) + 7(1+6k)<-2
\n" ); document.write( "-6 -42k +7 + 42k < -2
\n" ); document.write( "1<2\r
\n" ); document.write( "\n" ); document.write( "what am i doing wrong, my Ks went away?
\n" ); document.write( "

- 6(1 + 7k) + 7(1 + 6k) < - 2
\n" );
document.write( "- 6 - 42k + 7 + 42k < -2
\n" );
document.write( "1 < 2
\n" );
document.write( "You didn't do anything wrong. The variable, k went away, but as you can see the final \"product\" is an INEQUALITY that's TRUE. That's because - 42k + 42k = 0.
\n" );
document.write( "This means that you can substitute ANY VALUE for k and it'll be 1. I repeat, regardless of the value you substitute for k, the value on the left side WILL ALWAYS be 1. Try it!!
\n" );
document.write( "This means the INEQUALITY has:  \n" );
document.write( "

\n" );
