How do you find three consecutive even integers with a sum of -84. Please help!
mote1985 [20]
3 consecutive even integers : x, x + 2, x + 4

x + (x + 2) + (x + 4) = -84.....combine like terms
3x + 6 = - 84.......subtract 6 from each side
3x = -84 - 6
3x = - 90...divide both sides by 3
x = -90/3
x = -30

x + 2 = -30 + 2 = -28
x + 4 = -30 + 4 = -26

so ur 3 numbers are : -26, -28, -30
