The answer will be no Jason has changed the terms.
It is given that Jason changed the expression by using the cumulative property
The expression is given as
9+56b+3.4=34+5.6b+9
So from the cumulative property, we can only change the order but not the terms
a+b+c=c+b+a
So Jason has changed the terms as well
9+56b+3.4=34+5.6b+9
Thus the answer will be no Jason has changed the terms.
