- (y - 6) = - 1
Distribute the negative
- y + 6 = 1
Subtract 6
from both sides of the equation
Simplify
Subtract the numbers
- y = - 7
Divide both sides of the equation by the same term
- y = - 7
- y = - 7

Sorry! it took long i was switching classes
12=3x+6
is effectively c=ax+b
meaning
a is 3
b is 6 and
c is 12
So the "sum" means to add all of the terms: 1³ + 2³ + 3³
1³ is simply 1
2³ is 8
3³ is 27
so, from there, you just add all of those terms: 1 + 8 + 27 = 36
