I have just tried to solve the following simultaneous equation.(adsbygoogle = window.adsbygoogle || []).push({});

x + 2y = 5

x squared + y squared = 36

I guess that the 1st step is to rearrange the 1st equation to give:

x = 5 - 2y

From that point onwards I have no idea what to do! Can anybody guide me through this?

Thanks a lot!
