Answer:
Step-by-step explanation:
Let the number of blue marbles be x
The number of green marbles = 3x - 2
Total marbles= 18
x + 3x -2 = 18
4x - 2 = 18
4x = 18+2
4x = 20
x =20/4
x =5
The number of blue marbles = 5
The number of green marbles = 3*5 - 2 = 15 -2 = 13
12=2x6 or 12=6x2 either way it should be the same I hope this helps
