Let white marbles = x
Purple marbles = 5x + 2
Given:
x + 5x + 2 = 104
6x = 102
x = 17
Purple marbles = 5(17) + 2 = 85 + 2 = 87
Answer:
I would recommend using algebraic methods.
Step-by-step explanation:
Of course, guess and check takes a long time and is not very time efficient. If you're graphing it by hand, it'll take time and get tedious, and using algebraic methods will probably give you the most accurate answer. If you have access to a graphing calculator or graphing website like Desmos, then I would suggest using the program to check the answers you got using the algebraic methods.
Hope this helped :)
