three possible word problems for the equation 20-4x=-80

Sure! Here are three possible word problems that can be represented by the equation 20 - 4x = -80:

1. Sally has $20 and loses $4 for every toy she buys. After buying some toys, she realizes that she now has a total debt of $80. How many toys did Sally buy?
To solve this problem, we can set up the equation: 20 - 4x = -80. We need to find the value of x (number of toys), which represents the number of times Sally lost $4. By solving the equation, we can determine how many toys Sally bought to accumulate a debt of $80.

2. A student is solving an equation and comes across the equation 20 - 4x = -80. In order to solve the equation, they need to find the value of x. What is the value of x that satisfies this equation?
To solve this problem, we can directly use the given equation and solve for x. The resulting value of x will be the solution to this word problem.

3. The temperature is decreasing at a rate of 4 degrees per hour. If the temperature is currently 20 degrees, what will the temperature be after a certain number of hours, represented by x, has passed?
To solve this problem, we can use the equation 20 - 4x = -80. Here, x represents the number of hours passed, and 4 degrees are subtracted for each hour. By determining the value of x that satisfies this equation, we can calculate the temperature after a certain number of hours.
