John wrote that 5+5=10. Then he wrote that 5+5+n=10+n. Are the equations John wrote equivalent? Explain (in your solution justify by stating what property of equality he used).

They are equivalent

Step-by-step explanation:

n would equal the same, and 10 and 5+5 equal the same. Therefore, whatever n is, they will be equal no matter what. Unless you subtract the n from one side and add on the other.
