Answer:

C

Step-by-step explanation:

We can notice that the balance beam has in one side 7 balls and in the other one 5 balls and a square

The balance beam is balenced

Let x be the square mass

  • x+5 = 7            substract five from each side
  • x+5-5 = 7-5
  • x = 2

The solution is 2

C fits perfectly what we prooved
