Step-by-step explanation:
You can actually do this using various life scenario. Let me help you with this example.
Suppose that one person is called Mike and he needs to buy something, here is your scenario for Mike to get what he want:
Mike wants to buy a pair of shoes that worth 37$ for a soccer game next week. He only has 5$ in his wallet. In order to get the remaining money, he decides to work in a market for a day. If the market pay 8$ per hour, how many hours does Mike need to have enough money to buy the shoes?.
This is the real life scenario. The equation is as above, because you can call "x" the number of hours needed, so as you solve the equation, you'll realize that the number of hours needed is 4:
8x + 5 = 37
8x = 37 - 5
8x = 32
x = 32/8 = 4 hours needed.
