the sum of three consecutive even integers is -18 what are the integers?

Answer 1

Let Three consecutive evens be

2x

2x+2

2x+4

The sum is -18 so

2x+2x+2+2x+4=-18

Combine like terms

6x+6=-18

Subtract 6 from both sides

6x=-24

Divide by 6

X=-4

The 3 even consecutive numbers then are

2(-4)=-8

2(-4)+2=-6

2(-4)+4=-4
