Answer:
x = 3, y = 8.
Step-by-step explanation:
So if x = 3, and y = ?,
Its the same as if y = -4 when x = -9.
Find the difference between 3 and -9.
3 - (-9) = 12 because when you subtract a negative number, the second negative sign flips the direction your going on the number line. We just found the absolute value. Now the oppisite of 12 is -12. Final answer is -12.
Let's do the same thing to the -4, but subtract -12.
-4 - (-12) = 8.
So if x = 3, y = 8
