r = 95
b = 5g
r+g = b-189

95+g = 5g-189
4g = 284
g = 71
so, b = 355

95+71+355 = 521
red = 95
blue = 5 x green

red + green = blue -189

replace with what we know from above.

95 + green = 5 x green - 189

95 + g = 5g -189

194 = 6g
divide by 6 to find number of green.

Multiply that number times 5 to get the number of blue marbles.
