Pls help, what do I put in the blanks and what's the equation thank you

Answer:
-1 = -4
0 = -3
-5 = -8
-2 = -5
Step-by-step explanation:
What you are doing is adding -3 to each number. An equation will look like:
x+-3=y. You will then take the x and plug it into the x and you will find the y.
-1+-3=-4.
You will do this for each one.
