Let x represent the number of red marbles, then blue marbles are represented by x + 31
red + blue = 225
x + x + 31 = 225
2x + 31 = 225
2x = 194
x = 97
Blue: x + 31 = 97 + 31 = 128
Answer: 128 blue marbles

That means in total, they are the same but + 2.
Only 2c + 2 = 16 represents this.
Step-by-step explanation:
5 log₅ x − ¼ log₅ (8−x)
log₅ x⁵ − log₅ (8−x)^¼
log₅ x⁵ − log₅ ∜(8−x)
log₅ (x⁵ / ∜(8−x))
