Why should you only consider positive x values and y values on your graph?

If you are talking about length of an item it can only be positive.

If you talk about time it can only be positive.

If you talk about distance traveled it can  only be positive.

Things that cannot be negative in the real world, cannot be negative on the graph.

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
