The value is assigned to each of these variables after the last statement executes is x=1, y=102, z =15 and w =44.
A variable in terms of alphabets are unknown in the form of any mathematical expression and equations.
x = 7; y = 2 * (x - 3)
putting value of x =2 , we get
y=11
We have, z = x + y - 3
putting the value of x and y , we get
z=15
We have x = z / y
put the value of z, we get
x =1
We have y = z - x
putting the value of x and z , we get
y=14
We have w = x + y + 2 * z
substitute the value of x, y and z, we get
w =45
We have w--
w= 44
Using, y = 2 * w + z - x
put the value of x, z and w, we get
y= 102
Thus, x=1, y=102, z =15 and w =44
