Last problem! Can't figure it out!

Solve for n:
0.12 = (n - 6500)/6500

0.12 = (n - 6500)/6500 is equivalent to (n - 6500)/6500 = 0.12:
(n - 6500)/6500 = 0.12

Multiply both sides of (n - 6500)/6500 = 0.12 by 6500:
(6500 (n - 6500))/6500 = 6500×0.12

(6500 (n - 6500))/6500 = 6500/6500×(n - 6500) = n - 6500:
n - 6500 = 6500×0.12

6500×0.12 = 780.:
n - 6500 = 780.

Add 6500 to both sides:
n + (6500 - 6500) = 780. + 6500

6500 - 6500 = 0:
n = 780. + 6500

780. + 6500 = 7280.:
Answer: |n = 7280.

 0.12 = (n - 6500) / 6500

 

\( 0.12 =\frac{ (n - 6500) }{ 6500}\\ \text{multiply both sides by 6500}\\ \text{then add 6500 to both sides}\\\)
