b. These equations do not have a solution.

c. 5

Your help is a big time saver.

Answer 1

The value of variable y at the end is 7.

This is because the first line sets the value of variable x to 7. The second line assigns the value of x (which is 7) to y. The third line also assigns the value of x (which is still 7) to z. The fourth line assigns the value 5 to z, but this does not affect the value of y, which remains 7 since it was never changed.
