Answer: 2- (y= 6 , z=2)
Explanation:
If z = 4 and y = 6, then we can substitute these values into the expression:
z - (y - z) = 4 - (6 - 4)
Expanding the subtraction in the parentheses, we get:
z - (y - z) = 4 - (6 - 4) = 4 - (2) = 4 - 2
Finally, solving for the subtraction:
z - (y - z) = 4 - 2 = 2
So, the value of the expression z - (y - z) when z = 4 and y = 6 is 2.
