John and 3 friends are going out for pizza for lunch. they split one pizza and 4 large drinks. the pizza cost $12.50. they spend a total of $17.50. find the cost of one large drink.

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
