Question

Find three consecutive integers that have a sum of -39.

Answer 1

Answer: -14, -13, and -12

Step-by-step explanation: When thinking about consecutive numbers we think about numbers that are right next to each other. We also know that the word "sum"means adding by our signal words.

Since the sum of our three consecutive integers is -39, we can set up an equation to represent this.

X + X + 1 + X + 2 = -39

3x + 3 = -39

      -3     -3

3x = -42

÷3     ÷3

X = -14

X ⇒ -14

X + 1 ⇒ -13

X + 2 ⇒ -12

Therefore, our three concussive integers are -14, -13, and -12.
