Find three consecutive even integers whose sum is −24

labwork [276]

Answer: $-10,-8,-6$

Step-by-step explanation:

Let be:

$x$ , $x+2$ and $x+4$ the three consecutive even integers whose sum is -24

Then, we can write this expression:

$x+(x+2)+(x+4)=-24$

Now, we must solve for "x":

$3x+6=-24\\\\3x=-24-6\\\\3x=-30\\\\x=\frac{-30}{3}\\\\x=-10$

Then you get that the others integers are:

$x+2=-10+2=-8$

$x+4=-10+4=-6$

Therefore, the three consecutive even integers whose sum is -24 are:

$-10,-8,-6$
