Question

Ethan and his brother each sold the same number of raffle tickets they began with 42 tickets and after the sale is over and we're left with eight tickets know how many tickets did each other cell

Answer 1

For this case, we have initially had 42 tickets.

Then Ethan and his brother sold the same amount of tickets to end up with 8.

Then, we can propose the following equation:

`42-x-y = 8`

Where x and y represent the amount of tickets sold by Ethan and his brother respectively. Since each sold the same amount, then x = y:

`42-x-x = 8\\42-2x = 8\\42-8 = 2x\\34 = 2x\\x = \frac {34} {2}\\x = 17`

Thus, each sold 17 tickets.

Answer:

Each brother sold 17 tickets
