Question

-19 - 7n = -6(n + 4)

Answer 1

Hello from MrBillDoesMath!

Answer:

n = 5

Discussion:

-19 - 7n = -6(n+4)  =>                   Given

-19 -7n = -6n + (-6)(4) =>

-19- 7n = -6n - 24 =>                   Add 6n to both sides

-19 -7n + 6n = (6n -6n) - 24 =>

-19 -n = 0 -24 =>                         Add n to both sides

-19  (-n +n)  = n - 24 =>               Add 24 to both sides

(-19 +24) + 0 = n =>

+5 = n
