-10n + 3 = -117
Show work

Answer 1

`n = 12`

Explanation:

1) Subtract 3 from both sides.

`- 10n = - 117 - 3`

2) Simplify -117 - 3 to - 120.

`- 10n = - 120`

3) Divide both sides by -10.

`n = ( - 120)/( - 10)`

4) Two negative makes a positive.

`n = (120)/(10)`

5) Simplify 120/10 to 12.

`n = 12`

Therefor, the answer is n = 12.

Answer 2

Explanation:

move the constant to the right hand side and change its sign

-10 +3= -117-3

calculate the difference

-10n= -120

divide both sides by -10

-10 = -120

N= 12
