Step-by-step explanation:
You need to write 3 consecutive EVEN numbers using only one variable. multiply by 2 to ensure the numbers are even. Add or subtract 2 to get the next consecutive number.
(2x - 2) , (2x) , (2x + 2)
add them up to equal -78
-78 = (2x-2) + 2x + (2x+2)
-78 = 6x
-78/6 = x
-13 = x
the numbers are: (2(-13)-2) , 2(-13) , (2(-13)+2)
-28, -26 , -24
