Question

Find five consecutive integers such that:

Answer 1

Answer:

  17, 18, 19, 20, 21

Step-by-step explanation:

Let x represent the third (middle) integer. Then the first is (x-2) and the given relation is ...

  (x-2) + 3(x+1) = -39 +2((x-1)+x+(x+2))

  4x +1 = 6x -37 . . . . simplify

  38 = 2x . . . . . . . . . add 37-4x

  x = 19 . . . . . . . . . . divide by 2

The integers are ...

  17, 18, 19, 20, 21

______

Check

  17 + 3·20 = -39 +2(18 +19 +21)

  17 +60 = -39 +2(58)

  77 = -39 +116 . . . . . yes
