Answer:
It is x=−92 .
Step-by-step explanation:
1. Take out the constants
-(2 x 3 x 4 x 2)xxyy^3
2. Simplify 2 x 3 x 4 x 2 to 48
-48xxyy^3
3. Use Product Rule: x^ax^b = x^a+b
-48x^1+1y^1+3
4. Simplify 1 + 1 to 2
-48x^2y^1+3
5. Simplify 1 + 3 to 4
-48x^2y^4

I'm not 100% sure, as we don't do this at school here, but I think its :

2) (x, y) > (x-12, y+3)
3) (x, y) > (x+9, y-8)
