Jack's mother gave him 505050 chocolates to give to his friends at his birthday party. he gave 333 chocolates to each of his friends and still had 222 chocolates left. write an equation to determine the number of friends (x)(x)left parenthesis, x, right parenthesis at jack's party. find the number of friends at jack's party.

16

Okay, so Jack started with 50 chocolates and ended with 2. 
The simple way to calculate it would be by realizing that Jack only distributed 48 chocolates. We can find how many times 3 fits into 48 by dividing 48÷3=16.

Using algebra, we substitute the value we want to find with x. Here what we want to find is the number of friends that were at Jack's party.

We know that he started with 50 chocolates, then distributed 3× the number of friends present (which is x). 
We write that down as 50−3x 
(It's minus because when chocolates are distributed, Jack is taking away from what he has.)

We know that after this, there were only 2 chocolates left, so it's 
50−3x=2

Then we proceed by moving all the numbers to the right until only x is left:

−3x=2−50
−3x=−48

x=−48−3

x=16

Conclusion: The number of people that attended the party was 16.

The equation is 3x+2=50

There were 16 friends at Jack's party.
