please help me solve my homework with all the work involved. i have trouble paying attention in class so it's hard for me to do my homework. here are a few of the questions. I need to find out what the letters equal.
1.) 10(-4+y)=2y
2.)9(b-4)-7b=5(3b-2)
3.)-(8n-2)=3+10(1-3n)
4.)1/4(60+16s)=15+4s
Thank you a lot.

I'll do two of them for you. Which two would you like me to do?
The first two please
10(-4+y)=2y
-40 + 10y = 2y
-40 = 2y - 10y
-40 = -8y
-40/-8 = y
5 = y
_______________________
9(b-4)-7b=5(3b-2)
9b - 36 - 7b = 15b - 10
2b - 15b = 36 - 10
-13b = 26
b = -2
-40 + 10y = 2y
-40 = 2y - 10y
-40 = -8y
-40/-8 = y
5 = y

2b - 15b = 36 - 10

b = -2
