Answer: x=3, See the graph below
Step-by-step explanation:
SINCE THE QUESTION ASK FOR GRAPHING
See the graph below
-------------------------------------------------------------------
I AM ALSO GOING TO SHOW A SECOND WAY WITHOUT GRAPH FOR EXTRA
Given
y=6
y=3x-3
Use substitution (Substituting the value of y)
3x-3=6
Add 3 on both sides
3x-3+3=6+3
3x=9
Divide 3 on both sides
3x/3=9/3
x=3
Hope this helps!! :)

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
Let
n ----> the number of additional red circles
----> 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
