two consecutive sum -11

Question

two consecutive numbers sum of -11 the second number is four more than twice the first number find the two numbers

Answer 1

Let the two numbers be A and A+1, then A+A+1=-11, so 2A+1=-11 and 2A=-12, making A=-6. The two numbers are -6 and -5. Which one is the second number? Which one satisfies 2*(1st number)+4=2nd number? 1st number must be -5 because 2*(-5)+4=-6. So 1st number = -5 and second number = -6.
