Question 986370: is 7 a solution of n-3=4
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! If you mean n = 7, then replace every n with 7 like so
n - 3 = 4
7 - 3 = 4
4 = 4
Since 4 = 4 is true, this means n - 3 = 4 is true. So n = 7 is definitely a solution.
