Here is the answer sis lol
Answer:
-4y - 7x^3 + 2
Step-by-step explanation:
So first lets combine the y terms together, doing this we get:
-4y + 1 - x^3 - 3x^3 + 1 - 3x^3
Now lets combine the terms with x^3 together
-4y + 1 - 7x^3 + 1
Lastly, lets add the constants
-4y - 7x^3 + 2
Answer:
a.) x = -1.5, 1.5
b.) x = 2
c.) x = 1.5
d.) x = -1, 1
e.) x = -0.943, 0.943
f.) x = -0.447, 0.447
g) x = -0.75
h.) x = -5
