Question

-2(n+3)=13 solve for n

Answer 1

N= -8
This is the work :

Answer 2

Answer:

1. Simplify:

-2(n + 3) = 13
-2n - 6 = 13

2. Change „-6” side to right (to get answer), without forgetting to change the sign:

-2n - 6 = 13
-2n = 13 + 6
-2n = 19

3. Simplify (The „|” means operation done at both sides of equation):

-2n = 19 |:(-2)
n = -9.5

Proof:
-2(-9.5 + 3) = -2 * (-6.5) = 13

Hope this helps!
