Question

Find three even consecutive integers whose sum is -42
write an equation to model this situation

Answer 1

Answer:

let the consecutive even integers are x,x+2,x+4

given condition is

              x+x+2+x+4=-42

                 3x+6=-42

                  3x=-48

                  x=-16

then the numbers are  -16,-14,-12

Answer 2

Answer:

Let the integers be x, x+2, x+4.

ATQ- x + x+2 + x+4 = -42

         3x + 6 = -42

         3x = -42 - 6

         3x = -48

           x = $\frac{-48}{3}$

           x = -16

The even consecutive integers whose sum is -42 are -12, -14, -16.
