Answer:
n=2.5
Step-by-step explanation:
First, write an equation!
n+5n-6+2n+1=15
Now, combine like terms to make things easier.
8n-5=15
Cancel -5 from the left to isolate 5n as a variable.
8n-5+5=15+5
8n=20
Now divide both sides by 8.
8n/8=20/8
n=2.5

Answer:
A. 3x + (x+8) = -22 - 2x
Step-by-step explanation:
Let the number equal x.
Set up the first half of the equation.
The sum of three times the number and 8 more than the number can be written as:
3x + (x+8)
Sum means that you add the components.
Set up the second half of the equation.
The difference between -22 and twice the number can be written as:
-22 - 2x
Difference means subtraction, and because -22 is written first, that is the number that you subtract <em>from</em>.
If you set the halves of the equation equal, you get:
3x + (x+8) = -22 - 2x
Therefore, the answer is A.
