Given that:
a = b + c
b = x
c = y
Prove that:
a = x + y
The following properties may be helpful:
if b = x, then b + c = x + c
if c = y, then x + c = x + y
if the following are true:
- a = b
- b = c
then a = c
if the following are true:
- a = b
- b = c
then a = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
