N-7 divided by 9= -3
what number does n equal

-20

Step-by-step explanation:

If this is the question in number form: (n-7)/9 = -3

then...

n-7=-27

n=-20

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
