Lets x is the 1st consecutive even integers x +2 :the 2nd consecutive even integers x +4: the 3rd consecutive even integers
So sum of all 3 equals -78 then x + (x+2) + (x+4) = -78 x + x + 2 + x + 4 = -78 Simplify 3x + 6 = -78 Subtract (-6) to both sides 3x +6 -6 = -78 - 6 Simplify 3x = -84 Divided both sides by 3 3x/3 = -84/3
x = -28 x + 2 = -28 + 2 = -26 x +4 = - 28 + 4 = -24
Double check: -28 + -26 + -24 = -78
So the three consecutive even integers are: -24, -26, -28
