Step-by-step explanation:
Combine like terms and we get,

divide both sides of the equation by ax, and simplify further,
notice that we can reduce the 24 over 6 1/2,
distribute and simplify further
And a=
Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
