2n^2-6=-16
what am i supposed to be doing

n = ±i sqrt(5)

Step-by-step explanation:

2n^2-6=-16

Add 6 to each side

2n^2-6+6=-16+6

2n^2=-10

Divide by 2

2/2n^2 = -10/2

n^2 = -5

Take the square root of each side

sqrt(n^2) = sqrt(-5)

n = sqrt(-1) sqrt(5)

n = ±i sqrt(5)

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
