Is 2(–2) + 6(2) equivalent to (–3)(–3) + (–1)(1)?

Yes

Step-by-step explanation:

2(–2) + 6(2) =

-4 + 12 =

8

(–3)(–3) + (–1)(1) =

9 + -1 =

8

8 = 8, so they are equivalent

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
