Question

The sum of four consecutive integers is -18. What is the greatest of these integers?

Answer 1

Answer:

            - 3

Step-by-step explanation:

x       - the first of consecutive integers

x+1   - the second of consecutive integers

x+2   - the third of consecutive integers

x+3   - the fourth of consecutive integers (the greatest)

x + x+1 + x+2 + x+3 = -18

   4x + 6 = -18

       -6         -6

     4x = -24

     ÷4      ÷4

      x  = -6

     +3     +3

    x+3 = -3
