Which is the value of this expression when j= -2 and k= -1?

-64

Step-by-step explanation:

I just simplify the like terms to make it easier visually. After that, I plugged in j and k and solve for the answer which is -64.

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
