You can put this solution on YOUR website!
$600 = $425 - 7.50x
\n" ); document.write( "-425 = -7.50x
\n" ); document.write( "$175 = -7.50x
\n" ); document.write( "Missy can buy 23 CDs
\n" ); document.write( "Did compute this correctly. thank you\r
\n" ); document.write( "\n" ); document.write( "Yes you did get the right answer, however you had a negative number for X. in the first step you add 7.5X instead of subtrabtracting. In this way you wont get a negative number and will help you reduce any mistakes that often occur when working with and converting negative numbers.\r
\n" ); document.write( "\n" ); document.write( "so
\n" ); document.write( "$600=$425+7.5X
\n" ); document.write( "$600-425=7.5X
\n" ); document.write( "$175=7.5X\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
