53= 17n - 8n - 19
53 = (17n - 8n) - 19
53= 9n - 19
Add 19 to both sides.
72 = 9n
n = 8

53=17n-19-8n
53=9n -19 combine the two 'n's together 17-8=9
72=9n add 19 to both sides to get n alone
n=8 divide by 9 to get the value of n

53=17n-19-8n
53=9n-19 (combine like terms)
72=9n (add 19 to both sides)
8=n (divide by 9)

First, combine like terms (the n's). You get 9n-19=53
Now, add the 19 over. 9n=72
Finally, divide by 9 to get n alone. n=8!
