Let's solve this problem step-by-step:

   

  • x: it is the delta in the equation given in your picture

We know (7*10) - (7*x) is equivalent to the 7*(10-x)

 ⇒ based on the Distributive Properties

                             

         

 So:

   

Thus delta (the little triangle in this problem) in this case is 1

Answer: 1

Hope that helps!
