You "distributed" the negation inside the parenthesis. Let's focus on the 
part.
We can distribute the negation inside the parenthesis by negating every term, and switching and with or, and vice versa. So, you have
Of course, writing 
is improper, I was just stressing the fact that we distributed the negation to every term in the parenthesis. So, since a double negation cancels out, you're left with
which of course implies that
Edit: I actually derived the expression in the opposite order, but since they are equivalent, it doesn't really matters where you start from and where you get to. Anyway, if you actually want to derive 
from 
, you simply have to negate the first parenthesis and distribute the negation as discussed.
Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
I forgot what they’re called but the angles opposite to each other are the same degree. It’s a theorem, just search up the name
Answer:An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ( means Whole in Latin ) please give brainliest if possible
