x is equal to - 2/3 after collecting like terms
distributive property is when you take the number on the outside of the parenthesis and you, well, distribute it to the inside numbers.
so
35(5 + 7)
you have to do 35 * 5 and 35 * 7
its 175 and 245, and then you add those to get 420
same with 12
12 * 6 and 12 * 5
that's 72 and 60
72 - 60 = 12
you minus cause in the parenthesis it's a minus symbol in this case
please thanks if this helped or if u need more help just ask me

Answer:
A
Step-by-step explanation:
-(7/4) equals -7/4 or negative seven forths. Its doesn't matter where the negative sign is as long there's only 1 of them and that its still 7/4.
So through process of elimination, we take out B because theres 2 negative, which make a positive, our answer is negative
C is wrong because its 4/7, not 7/4
D is wrong because it's positive, leaving us with A
