Explanation: Sam has x cards and Alesia has 2 times the amount of cards Sam has plus 20 more, so the equation will be x + (2x + 20). Then it went on to say Farid has 3 times the card Alesia has. That’s would be written has ((2x +20) x 3), why do we write it like this? Because we are doing two working, the amount Alesia had times 3 would represent Farid’s amount.

The equation that represents the total number of card for all three people is 9x + 80 = 350

Sam has x number of trading cards.

Alesia has double the number of cards as Sam plus 20 cards more. Therefore, Alex has the following card:

  • 2x + 20

Farid has triple the number of cards as Alesia .Therefore, Farid number of card is as follows:

  • 3(2x + 20)

In total they have 350 cards. Therefore, the equation that represent the total number of cards is as follows;

x + 2x + 20 + 6x + 60 = 350

9x + 80 = 350

9x = 350 - 80

9x = 270

x = 270 / 9

x = 30

The equation that represents the total number of card for all three people is 9x + 80 = 350
