system of linear equations by the substitution method

[sweetchildkisses]

I am trying to solve the system of linear equations by the substitution method.

3x = –11y - 53
3x + 8y = –41

I am getting (5,–7). Does this seem right?

Simply sub them back in and see if they check out.

… (5,–7). Does this seem right?

No, it does not seem right.

Please show your work.
