Question

-8n plus -4n equals-72

Answer 1

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

$\frac{12n}{12}=\frac{72}{12}$

$n=6$

Therefore the value of n in the given equation is 6

Therefore n=6
