Which of the following is not a linear equation in one variable?
a) 33
b) 33(x+y)
c) 33x
d) 33y

- Option b) 33 (x + y) is not a linear equation in 1 variable.
- Here, we can see that there are 2 variables used ⇨ x & y. Hence, even though it's a linear equation, it's not in 1 variable.
- All the other options are in 1 variable or don't have a variable at all.
