Answer :
Answer:
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
