Hi you did not add the information of the different prices for the whistles I'm sorry to say without the information I cannot answer this I recommend reposting this with the correct information such as the price of the whistles so possibly me or someone else can help you

Step-by-step explanation:

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
