Answer:
x=26
Explanation:
1. (3-4) + x = 25
2. 3-4=-1
3. -1+x=25
4. -1+26=25
Let X represent the number we don't know, so X in this equation would equal 26 because -1+26=25 and 25 is the number we are trying to equal. I hope this helped. Let me know if I need to explain something else you don't understand in this equation, hope this helped! xx
