The sum of 8n^2-3n+10 and -3n^2 -6n-7 is

8n^2-3n+10 + -3n^2-6n-7

8n^2 + -3n^2 = 5n^2

-3n + -6n = -9n

10 + -7 = 3

Put them all together and you get 5n^2-9n+3

I tried to space them out so that it makes more sense.

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
