Kate Ramsey · Answer 1

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
