Answer:
The number of red circles to be added would be equal to 8 times the original amount of red circles
Step-by-step explanation:
Let
x ----> the number of red circles
y ----> the number of blue circles
Originally

----> equation A
How many more circles would need to be added to make the ratio of red to blue 3:1

----> equation B
substitute equation A in equation B

solve for n

therefore
The number of red circles to be added would be equal to 8 times the original amount of red circles
