Answer:
n = -3
Explanation:
Simplifying 
11(n + -1) + 35 = 3n 
 
Reorder the terms: 
11(-1 + n) + 35 = 3n 
(-1 * 11 + n * 11) + 35 = 3n 
(-11 + 11n) + 35 = 3n 
 
Reorder the terms: 
-11 + 35 + 11n = 3n 
 
Combine like terms: -11 + 35 = 24 
24 + 11n = 3n 
 
Solving 
24 + 11n = 3n 
 
Solving for variable 'n'. 
 
Move all terms containing n to the left, all other terms to the right. 
 
Add '-3n' to each side of the equation. 
24 + 11n + -3n = 3n + -3n 
 
Combine like terms: 11n + -3n = 8n 
24 + 8n = 3n + -3n 
 
Combine like terms: 3n + -3n = 0 
24 + 8n = 0 
 
Add '-24' to each side of the equation. 
24 + -24 + 8n = 0 + -24 
 
Combine like terms: 24 + -24 = 0 
0 + 8n = 0 + -24 
8n = 0 + -24 
 
Combine like terms: 0 + -24 = -24 
8n = -24 
 
Divide each side by '8'. 
n = -3 
 
Simplifying 
n = -3
