Answer:
The value of n in the given equation is 6
Therefore n=6
Step-by-step explanation:
Given expression is -8n+(-4n)=-72
To simplify the given expression as below :
-8n+(-4n)=-72
-8n-4n=-72
-(8n+4n)=-72
Dividing by (-) on both sides we get
8n+4n=72
12n=72 ( adding the like terms )
Dividing by 12 on both sides we get
[tex]\frac{12n}{12}=\frac{72}{12}[/tex]
[tex]n=6[/tex]
Therefore the value of n in the given equation is 6
Therefore n=6
