Jason is solving a problem about his savings. He has a certain amount of money in his piggy bank. If he adds $15 to his savings, he will have a total of $50.
We can set up an equation to find out how much money Jason originally had in his piggy bank. Let x represent the amount of money Jason originally had. The equation can be written as:
$$x + 15 = 50$$
What is the value of x?
