Answer 2

Answer:

n=-9

Step-by-step explanation:
In order to solve for x, we must get x by itself on one side of the equation.
The equation is:
-8-5n=64+3n
5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation.
-8-5n+5n=64+3n+5n
-8=64+3n+5n
-8=64+8n
64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation.
-8-64=64-64+8n
-8-64=8n
-72=8n
n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8.
-72/8=8n/8
-72/8=n
-9=n

The solution to the equation is n=-9
