Prove the Addition Property of Equality using a = 8 and b = 8

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 = 8 and c = 9, we set b = 8:

a + c = 8 + 9

b + c = 8 + 9

Evaluating, we get:

a + c = 17

b + c = 17

Final Answer


Since 17 = 17,
we have proven the Addition Property of Equality
using a and b = 8 and c = 9.
