My parents bought a house and the EMF readings are really high. It seems that the source is outside the home in a certain direction. How can we find out what the source is and what can we do to protect ourselves from the EMF? Also, are there professionals that deal with this? What is their professional title?

I can't get the answer to this problem! well, i know how to do it, but the numbers are weird and my online hw program says it's wrong! I tried 2 diff answers and only have one try left. Help!

Solve this systems of equations by substitution:
3x+5y = -19
2x+7y= -31

it's not y = (131/11) and x = (-288/11) or ugly numbers like that cuz i input those and it was incorrect..but did anyone else get that?? thanks!
