First Question: 63 coins are not nickels.
Second Question: 63+n=91
Step-by-step explanation:
For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.
For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.
Hope that this helps! Good luck with what you're working on!
