You can put this solution on YOUR website!
In order to isolate the variable you have to get rid of the -13. To do that you need to +13 to both sides of the equation. \r
\n" ); document.write( "\n" ); document.write( "k-13(+13)=29(+13) Then do the math. \r
\n" ); document.write( "\n" ); document.write( "The -13 and the +13 equal zero so they cancel each other out leaving just the k on that side of the equation. Then simply add 29+13.\r
\n" ); document.write( "\n" ); document.write( "k=42\r
\n" ); document.write( "\n" ); document.write( "Of course you can always check that answer. 42-13=29 ??? Yes :) \r
