  2. y is subtracted from 7y
  3. 7 is subtracted from y
  4. None of the above

Hint:

The given equation is algebraic expression. It contains a variable y. Variable means a quantity which doesn't have fixed values. And the constant in the equation is 7. A constant has a fixed value. We have to find the operation between the variable and the constant.

The correct answer is: 7 is subtracted from y


    The given equation is y-7.
    The sign between the variable and constant is minus. Minus sign represents subtraction. It means we subtract one quantity from the other. In the above equation, the minus sign is before 7. It means we are subtracting seven from the variable y.
    Therefore, option (c), which is '7 is subtracted from y' is the right option.
