How do u solve this equation: (15 – n) + (12 – n) = 13?

Question

How do you solve this equation 15 – n) + (12 – n) = 13

Answer 1

15-n+ 12-n= 13

-2n +27= 13

-2n= 13-27

-2n= -14

n= -14/-2

n= 7

Answer 2

(15 - n) + (12 - n) = 13

27 - 2n = 13

-2n = -14

n = 7

Answer 3

15n - n + 12 - n = 13

            27 - 2n = 13

                  -2n= 13 - 27

                  -2n= -14

                     n= -14/-2

                     n= 7

easy!

Answer 4

15-n+12-n=13

gather like terms,

-2n+27=13

solve for n,

-2n=-14

n=7

Answer 5

u ask a math teacher lol  

Answer 6

15-n+12-n = 13 separate the numbers from the variables

15+12-n-n=13

27-2n=13 move the variables in the right side, and the numbers in the left side, not forgetting to switch signs.

27-13=2n

14=2n divide by 2

n=7
