A bag contains green marbles and blue marbles, 68 in total. The number of green marbles is 2 less than 4 times the number of blue marbles. How many green marbles are there?

Green Marbles = G = 54

Step-by-step explanation:

Total Marbles = 68

Suppose

Blue Marbles = B

Green Marbles = G

According to given information

G = 4B - 2

We know

G + B = 68

Put value of G in this equation

4B - 2 + B = 68

5B = 70

B = 14

Put value of B in  "G + B = 68"

G + 14 = 68

G = 68 - 14

Green Marbles = G = 54
