A bag contains white marbles and yellow marbles, 54 in total. The number of white marbles is 6 less than 3 times the number of y

NNADVOKAT [17]

Let x be white marbles, y be yellow marbles
x+y=54…(1)
x=3y - 6 …(2)

put (2) into (1)
(3y - 6) + y = 54
4y = 60
y=15

put y=15 into (1)

x + 15=54
x=39

so y=15 x=39
