Question

Three consecutive integers have a sum of –21. Which equation can be used to find the value of the three numbers? x + x + x = negative 21 x + 2 x + 3 x = negative 21 x + (x + 1) + (x + 2) = negative 21 x + (x + 2) + (x + 4) = negative 21

Answer 1

Answer:

The equation which can be used to find the value of numbers

(x) + (x + 1) + (x + 2) = - 21

Step-by-step explanation:

Let the first no. is =  x

Second number = x + 1

Third number = x + 2

The sum of three consecutive numbers = x + x + 1 + x + 2

Given that Three consecutive integers have a sum of –21.

Therefore

(x) + (x + 1) + (x + 2) = - 21

This is the equation which can be used to find the value of numbers.

Answer 2

Answer: x + (x + 1) + (x + 2) = -21
