Question

ok who can help with this one

Answer 1

The correct answer is -4. I just inputted numbers randomly around the center point of 0 and saw that -4*2 + 3 = 5 and -4 - 1 = -5. Since they both have the same numerator,
all you have to do is solve for the denominator which would result the answer to be -4.

Answer 2

Cross multiply.
What do you get?

Answer 3

I ended up getting the same thing as Shadow -4

Answer 4

No Problem? :D
