Answer 1

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
