Other answers:

no it cant be. -7 doesnt solve that equation
so i got D
see, there is a little trick you can use. With just two substitutions you can determine which is the correct answer. Suppose you substitute 7 in the equation, it solves it. so the answer is either C or D. next substitute 8/5. it doesn't solve the equation. So it is not D. so your answer has to be C
