Find the value of this expression if x=-7 x^2+5/x+1

-9

Step-by-step explanation:

Substitute -7 for x. So we get ((-7)^2+5)/(-7+1). We start with the exponent. (-7)^2 is 49. Then we add 5 to that, and get 54. -7+1 is -6. So we have 54/-6, which is equal to -9.

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
