Choose 2 of the following equations and create a real-life situation that can be represented by it. Try to have fun with this! :)
x + 6 = 15
-3 + x = 10
5x = 20
x/4 = 8
Equation: x + 6 = 15
Real-life situation: Let's say you are planning a surprise party for a friend. You have 6 friends who have already RSVP'd and you want to make sure you have enough food for everyone. You realize that you need a minimum of 15 people to attend the party to make it successful. You need to find out how many more friends you need to invite, so you set up the equation x + 6 = 15, where x represents the number of additional friends you need to invite. By solving the equation, you find that you need to invite 9 more friends to make a total of 15 attendees for the surprise party.
Equation: 5x = 20
Real-life situation: Suppose you are at a store shopping for t-shirts. The store is having a sale where each t-shirt costs $5. You want to buy some t-shirts for yourself and your friends. You need to find out the total cost of the t-shirts you want to purchase, so you set up the equation 5x = 20, where x represents the number of t-shirts you want to buy. By solving the equation, you find that you can buy 4 t-shirts with a total cost of $20.
