Answer: n=−6
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 
 
 2-4+n/3-(-4)=0 
simplify n/3
(-2+n/3)- -4=0
Rewrite the whole as a fraction using 3 as the denominator : 
 
 -2 • 3 
 -2 = -2/1 = -2X3/3 
 
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole 
 
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
-2 • 3 + n /3=n-6/3
 n+6 = 0 
 
 Subtract 6 from both sides of the equation : 
 n = -6
