Given that:
(a + b) + c = d
Prove that:
a + c = d + (b ⋅ (-1))
The following properties may be helpful:
if (a + b) + c = d, then (b + a) + c = d
if (a + b) + c = d, then b + c = d + (a ⋅ (-1))
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.
