Step-by-step explanation:
<em>Commutative property</em>:-
the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.
Let 'a' and 'b' be the two integers , then ab = b a
Example:-
. 1 X 2 = 2 X 1 = 2

B is the right hope it help
Answer:
x=1
x=-5
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem there are two intersection points
so
The system has two solutions
we have
one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)
see the attached figure
therefore
x=1
x=-5
