Accounts Receivable 500 Cost of Goods Sold (COGS) 275 Inventory 275 Sales Revenue 500 Explanation: When you see goods and the customer receives them, you can book revenue for the amount that the customer owes. Revenues are increased with a credit. Since the customer paid on credit, you have not yet received cash. The customer owes you \$500 in the form of an asset, which is increased with a debit. The backpacks are on your inventory list for the amount it cost you to purchase them. This is the \$275. When you sell them, you will empty out the inventory which is an asset. You decrease your asset with a debit. When you sell items, you must incur an expense for how much the goods cost you. This is called Cost of Goods Sold. This expense is increased with a debit.

Lauren J.

To solve a sequence of equations you need to separate out one variable. Step 1: subtract 7 from both sides to separate x 2y=x+7 -7 -7 2y-7=x Step 2: Plug in this equation into the first equation. 2(2y-7)+3y=21 Step 3: solve this equation to separate out the y-variable 4y-14+3y=21 +14 +14 4y+3y=35 7y=35 y=5 Step 4: Plug y into the second equation to solve for x 2y-7=x 2(5)-7=x 10-7=x 3=x Final Answer: x=3, y=5
