Which of the following is not a linear equation in one variable?

a) 33

b) 33(x+y)

c) 33x

d) 33y

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

• 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.
