Math Problem Statement

The sum of 3 consecutive integers is -63. Find the integers.

Solution

The problem from the image states:

"The sum of 3 consecutive integers is -63. Find the integers."

Let's set up an equation for this:

Let the three consecutive integers be:

  • xx (the first integer),
  • x+1x + 1 (the second integer), and
  • x+2x + 2 (the third integer).

The sum of these integers is given as -63: x+(x+1)+(x+2)=63x + (x + 1) + (x + 2) = -63

Simplify the equation: 3x+3=633x + 3 = -63

Subtract 3 from both sides: 3x=663x = -66

Now, divide both sides by 3: x=22x = -22

So, the three consecutive integers are:

  • x=22x = -22
  • x+1=21x + 1 = -21
  • x+2=20x + 2 = -20

Therefore, the integers are -22, -21, and -20.
