The following problem raises some questions to me as to how the answer came to be:

7(x+4) (greater than or equal) 6(x-3)+x

After going through the problem I end up with an answer of:

0 is (greater than or equal) to -46

Not sure whats happening here because when I look up the answer I see it charted on the line from end to end going outward and an answer of

(-infinity sign, infinity sign)
