Step-by-step explanation:
3 chocolates each or 3x because what "each" means is not known yet-
3x
Note: Always use x for an unknown value
2 remaining chocolates-
3x + 2
50 total chocolates-
3x + 2 = 50
Remove two to keep the x alone-
3x = 48
Remove the 3 or the "Coefficient" by dividing-
48/3 = 16
x = 16
Equation: 3x + 2 = 50
