Can someone help me here?

I need to solve the system by addition or substitution

3x - 4y = 8
6x - 2y = 10

Thanks,
Jamie Determine if this is rational or irrational:

sqrt 77

This would be rational correct? I know 11 can go in to but it is as well and odd number, so i am not real sure. Thank you for the help!
