I think it is 0
6= 1-2(0)+5
6=1-0+5
6=1+5
6=6

The question is incomplete, here is the complete question:
You and your friend are selling magazine subscriptions. You sell 8 fewer magazine subscriptions than your friend. Together you sell 42 magazine subscriptions. Write a system of linear equations that represents this situation.
The system of linear equations that represents this situation is:
x + y = 42
x - y = 8
Step-by-step explanation:
To solve the problem assume that
- x represent the number of magazine subscriptions that your friend sell
- y represents the number of magazine subscriptions that you sell
∵ Your friend sells x magazine subscriptions
∵ You sell y magazine subscriptions
∵ Together you sell 42 magazine subscriptions
∴ x + y = 42 ⇒ (1)
∵ You sell 8 fewer magazine subscriptions than your friend
∵ Your friend sells x magazine subscriptions
∵ You sell y magazine subscriptions
- That means y = x - 8
∴ y = x - 8
- Add 8 for both sides
∴ 8 + y = x
- Subtract y from both sides
∴ 8 = x - y
- Switch the two sides
∴ x - y = 8 ⇒ (2)
The system of linear equations that represents this situation is:
x + y = 42
x - y = 8

10 times the sum of 2 and 1 is represented by the following expression:
10 x (2 + 1)
10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".
The answer is x=3
I just put the variables on one side and the whole numbers on the other and solved for x
I believe it is 2,400. 4,000 x 0.6 = 2,400
