x = the first integer
x + 1 = the second integer
x + 2 = the third integer.
Let's set each of our variables equal to -69
x + x + 1 + x + 2 = -69
Combine like terms
3x + 3 = -69
Subtract 3 from both sides.
3x = -72
Divide both sides by 3
x = -24
The first integer = x = -24
The second integer = x + 1 = -24 + 1 = -23
The third Integer = x + 2 = -24 + 2 = -22
