Answer:
yeah draw a big marble that contains each color of these marbles , 3 blue ,4 green , 5 red. try it!
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
Im pretty sure it can. 20 +20 = 40. if that helps...
