You start out with 20 and then spend money in a store where every item is 3. Y -3x 20.?

To solve the equation ( Y - 3x = 20 ), where ( Y ) represents your remaining money and ( x ) is the number of items purchased, we can rearrange it to find ( Y ). If you spend 3 for each item, then after buying ( x ) items, your remaining money will be ( Y = 20 - 3x ). This means that for every item you buy, your total decreases by 3 from your original 20.
