We perform the following assignment commands: x:=1; y:=9; z:=x+y; z:=z*y; The result is

"z" in z=x+y is 10. The first "z" in z=z*y equals 90.

Explanation:

Let's start with the first equation, z=x+y. Since we have our given values, all we have to do is add them. If "x" is 1 and "y" is 9, adding 1+9 gives us 10.

Now for the second equation, z=z*y. Since we have both values on the right hand side of the equation, we can already multiply to get our answer. The second "z" in the equation is the answer of "z" in the first equation, which is 10. Since "y" equals 9, multiplying 10 by 9 yields us 90.

Hope this helps buddy!

i don't think so. although it would be nice. i am pretty sure that was an option an update or two ago. i guess they want you to stay 14 forever. haha.
