Given that:
b + c = 0
Prove that:
(a + b) + (c + d) = a + d
The following properties may be helpful:
- (a + b) + c = (a + c) + b
- a + (b + c) = (a + b) + c
- ((a + c) + d) + b = ((b + c) + a) + d
- 0 + a = a
if a = b, then a + c = b + c
if the following are true:
- a = b
- b = c
then a = c
if a = b, then a + c = b + c
if the following are true:
- a = b
- b = c
then a = c
if a = b, then a + c = b + c
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.
