Question

Alvin,Benjamin and Chloe share some marbles. Alvin has 12 less marbles than Benjamin,who has four times as many marbles as Chloe. They have a total of 42 marbles. Find the number of marbles Chloe has.​

Answer 1

Alvin=12
Benjamin=24
Chloe=6

Answer 2

Answer:

Step-by-step explanation:

Let Benjamin marble = x

Alvin marble = x - 12

Chloe marble = x/4

Total marble = 42

X + X - 12 + X/4 = 42

2X + X/4 = 42 + 12

2X + X/4 = 54

MULTIPLY EACH TERM BY 4

8X + X = 216

9X = 216

X = 216/9

X = 24

Chloe marble = X/4 = 24/4 = 6
