Answer:
Equation: 3x+2=50
Number of Friends: 16
Explanation:
Because it says that he had 50 chocolates so 50 is your total amount then he gave 3 chocolates to each of his friends but since u do not know how many friends he gave the chocolates to it becomes your x so 3x and he had 2 left so your equation is 3x+2=50. To find the number of friends solve the equation or the simple way do 50-2=48 then 48 divided by 3= 16
