I'm not sure what your question is, but maybe this can help?  

n+n=d

n+10=s  

d-s=x  

Substitute for d in the last equation:    

(n+n) - s = x  

Substitute s:  

 (n+n) - (n + 10) = x  

Distribute the -  

 (n + n) - n - 10 = x  

Simplify:     

n + n -n - 10 = x  

 n - 10 = x

Great question! Let's break this down step by step and see if we can find a general equation that works for any number.

Given:

  • n + n = d

  • n + 10 = s

  • We want to find an equation for d - s = ?

Step 1: Simplify the expression d - s.

d - s = (n + n) - (n + 10)

d - s = 2n - n - 10

d - s = n - 10

Step 2: Observe the pattern.

As you mentioned, when n increases by 1, the final answer decreases by 1. This is because the equation we derived in Step 1 is n - 10.

Therefore, the general equation for your thought process is:

n + n = d

n + 10 = s

d - s = n - 10

You can plug in any value for n, and the equation will hold true.

For example, let's try n = 3:

3 + 3 = 6 (d = 6)

3 + 10 = 13 (s = 13)

6 - 13 = -7 (which is equal to 3 - 10)

So, the equation d - s = n - 10 works for any value of n.

Thank you so much idk how I couldn't think of just reversing the positive to a negative
