-(5n-9)+3n=-2(5n-20)<br> what is n?
11Alexandr11 [23.1K]

Answer:

n=3.875

Step-by-step explanation:

First, we can expand the brackets:

-(5n-9)+3n=-2(5n-20) (given)

-5n+9+3n=-10n+40

-2n+9=-10n+40 (combine like-terms)

8n=31

n=3.875

Hope this helps :)

Solve for x.<br> (x - 3)^2 -10 = 15
Brut [27]

Answer:

Step-by-step explanation:

Let's go:

(x - 3)^2 - 10 = 15 \\\ (x - 3)^2 = 15 + 10 \\\ (x - 3)^2 = 25 \\\ x - 3 = \sqrt{25} \\\ x - 3 = \pm 5

Solution #1:

x - 3 = 5

x = 5 + 3

x = 8

Solution #2:

x - 3 = - 5

x = - 5 + 3

x = - 2

I hope I helped you.
