How can x+3=-2x+5 be set up as a system of equations

  and

Step-by-step explanation:

Consider, one set of equation as:

          (1)

and the another set of equations as:

      (2)

From (1) and (2) we can see that the Left hand side is same, therefore equating the right hand side, we get

which is as given in the question.

Thus, can be set up as  and set of equations.

3=log(n)=2

answer a: product property
