Fill in a number in each of the two spaces, that is, the sum of the first two numbers is 3 less than the sum of the last two numbers, and the sum of the three numbers is 0 ()()-2

Fill in a number in each of the two spaces, that is, the sum of the first two numbers is 3 less than the sum of the last two numbers, and the sum of the three numbers is 0 ()()-2

Let the first be x and the second be y
From the sum of the first two numbers is 3 less than the sum of the last two numbers
x+y+3=y+(-2)
It's time to make an appointment
x+3=-2
x=-5
And because the sum of the numbers is zero
-5+y+(-2)=0
So y = 7
So the answer is
-5 7 -2
