Answer 1

d is the answer, using the commutative property

Hope my answer helps!

Answer 2

Using commutative property, a + b = d = b + a




Method 2 :

$a + b = d \\ \\ => a = d - b \: \: \: \: \: \: \: \: \: \: ..(i) \\ \\ \\ hence \\ \\ \: b \: + a \\ \\ => b + d - b \: \: \: \: \: \: \: \: \: \: (from \: \: (i) \: \: \: \: ) \\ \\ = > d \\ \\ \\ \\ \mathbf{Answer : d}$
