Alex had Y toy cars. He gave 11 of them to his friend. Later his dad bought him twice as many toy cars as he had in the beginning. How many toy cars did Alex have in the beginning of this story if now he has 55 of them?

Alex had 22 toy cars in the beginning of this story

Step-by-step explanation:

Initially, Alex had Y cars.

He gave 11 of them to his friend.

So then he had Y - 11 cars.

Later his dad bought him twice as many toy cars as he had in the beginning.

Now he had Y - 11 + 2Y = 3Y - 11 cars.

How many toy cars did Alex have in the beginning of this story if now he has 55 of them?

Now we have that:

3Y - 11 = 55

3Y = 66

Y = 66/3

Y = 22
