What does n represents
In arithmetic, the number that divides another is referred to as divisor;
Take for instance;

This implies that when 5 is divided by 3, the remainder is 2
The bold text (divided by 3) means that 3 is the divisor of 5;
When compared to 
We have that
n = 3
<em>Reason being that, n and 3 are in the same position base on order of appearance;</em>
Hence, n represents the divisor
1. Subtract 4 from both sides
v - 4 = 2t
2. Divide both sides by 2
v - 4/2 = t
3. Switch sides
t = v - 4/2
13x + 13 + 2x = 2
15x + 13 = 2
15x = -11
