Assume that you could fold the paper as many times as you want. How many
folds would be required for the paper to be taller than Mount Everest at
8850 meters? (Hint: Use a calculator to generate two large powers of 2 and check
if the required number of millimeters is between those two powers. Continue
to refine your guesses.)

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
