You can put this solution on YOUR website!
First solve for x using the equation:
\n" ); document.write( ".
\n" ); document.write( "\"%28-1%2F3%29x+%2B+7+=+16\"
\n" ); document.write( ".
\n" ); document.write( "Subtract 7 from both sides to get:
\n" ); document.write( ".
\n" ); document.write( "\"%28-1%2F3%29x+=+9\"
\n" ); document.write( ".
\n" ); document.write( "Then get x by itself on the left side by multiplying both sides by -3. When you do that
\n" ); document.write( "multiplication the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "\"x+=+-27\"
\n" ); document.write( ".
\n" ); document.write( "Now that you know the value of x from the first equation, you can substitute that value into
\n" ); document.write( "the expression \"2x+%2B+1\" to get the answer to your question. When you do the substitution
\n" ); document.write( "the expression becomes:
\n" ); document.write( ".
\n" ); document.write( "\"2%2A%28-27%29+%2B+1+=+-54+%2B+1+=+-53\"
\n" ); document.write( ".
\n" ); document.write( "The answer to this problem is -53 which means that answer C is correct.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the problem.
