Question

-21=-3(n+4)-6(-n-2) with the steps please

Answer 1

n = - 7

distribute the brackets on the right side of the equation and simplify

- 21 = - 3n - 12 + 6n + 12

- 21 = 3n

divide both sides by 3

`(- 21)/(3)` = n ⇒ n = - 7

Answer 2

-21 = -3(n + 4) - 6(-n - 2)

-21 = -3n - 12 + 6n + 12 distributed the -3 and the -6 on the right side

-21 = 3n added like terms (-3n + 6n) and (-12 + 12)

`(-21)/(3) = (3n)/(3)`

-7 = n

Answer: n = -7
