d. 2/3

  1.  B. 1:3

2.  A.

Step-by-step explanation:

1. Given : Rachel has 6 pairs of black shoes and 2 pairs of red shoes.

paula, cory, and krista

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
