Respuesta :
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
