Question

Three consecutive integers have a sum of –21. Which equation can be used to find the value of the three numbers?

Answer 1

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

Almost positive thats the right answear

Answer 2

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

combine like terms

3y +3 = -21

subtract 3 from each side

3y = -24

divide by 3

y = -8

y+1 = -7

y+2 = -6

Answer: -8, -7, -6
