So, in this case,
Now, negative exponents works like positive exponents, except you have to invert the number: i.e.
So, you have
8 ≥ y + 3 is the answer to problem 7. Also, in problem 5, I couldn't help but notice that the sign should face the other way but still include the equal to sign underneath it, because it should be 4 at MOST, meaning that 4 must be greater than or equal to y + 7.
