Answer:
There are 6 colered chips in the box
Step-by-step explanation:
To solve the problem we have to try to pass the words to simpler equations
t = total
r = red chips
b = blue chips
y = yellow chips
t - 4 = r
t - 4 = b
t - 4 = y
r + b + y = t
now that we made the equations we can work with them to find the value of t
(t - 4) + (t - 4) + (t - 4) = t
3t - 12 = t
3t - t = 12
2t = 12
t = 12/2
t = 6
