Answer:
y=7
Step-by-step explanation:
-6y= -27-15
-6y= -42
y=7
For this case we have the following polynomials:

To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
Note: see attached image for the solution.
Bob76 this is a really good answer. I don't know much about this though.
Step-by-step explanation:
11.3x-12 for x=5
=3(5)-12
=15-12
=3
12.45+15(n-1) for n=6
=45+15(6-1)
=45+15(5)
=45+75
=120
