Now answer me that question because I will search them but I will not find them

27: -5/11

28: 4x^2+12x

29: (2b-7c+5a)(2b-7c-5a)

30: 2/3

Step-by-step explanation:

27 is pretty simple, start by multiplying both sides by 6

so we have 2(6y+1)=y-3

this equal 12y+2=y-3

Subtract 1y and 2 from both sides to get

11y=-5

divide and get y= -5/11

28: this one is a lot to write so if you need me to explain it leave a comment but I got 4x^2+12x

29: Same deal as 28

(2b-7c+5a)(2b-7c-5a)

30: For this one I just distributed then combined like terms to get y=2/3

for the points
