Prove the Addition Property of Equality using a = 5 and b = 5

Equality means equal

Addition Property of Equality Definition:

For three numbers a, b, and c:
If a = b, then a + c = b + c

Plug in a = 5 and c = 6, we set b = 5:

a + c = 5 + 6

b + c = 5 + 6

Evaluating, we get:

a + c = 11

b + c = 11

Final Answer


Since 11 = 11,
we have proven the Addition Property of Equality
using a and b = 5 and c = 6.
