Yn+13=k
n= ?

ILL MARK BRAINLIST

Both solutions work!

Step-by-step explanation:

We are given the equation:

To solve or isolate the n-term — first, we subtract 13 both sides.

Since we want to isolate n-term, we divide both sides by y-term.

Alternate Solution

The answer above is correct, but for this alternate solution, we will simplify or separate the fraction.

From the equation n-isolated:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
