Alex,Gil And Meg Shared 740 Cards.Alex Had 20 Fewer Cards Than Gil And 120 Fewer Cards Than Meg. How Many Cards Did Alex Have?

Jawaban: #1:

Alex's cards are 200 cards

Pembahasan

DIketahui:

Total of the cards = 720

Alex's cards = Gil's cards - 20

Alex's cards = Meg's cards - 120

Ditanya: Alex's card

Dijawab:

Alex's card = x

Gil's card = y

Meg's card = z

x = y - 20

y = x + 20

x = z - 120

z = x + 120

Total of the cards = x + y + z

740 = x + x + 20 + x + 120

740 = 3x + 140

3x = 740 - 140

3x = 600

x = 200

So, the cards that Alex have are 200
