Extracted text: A variable in a program is a named placeholder that can contain any integer value. The statementz + e replaces the old value of the variable x with the result of evaluating the expression e. For example, if x initially contains 7 then the statement I + 1 +1 results in x containing 8. If the variables x, y and z initially contain the values 7, -2, and 8 respectively. What will be the value of y after the following statements are executed, in order, twice: I + I + z - y - y + z 2 O -19 35 29 21 O None of the other answers are correct
