A linear equation in one variable, has is only one variable involved.
In 33(x + y) = 0, there are 2 variables x and y.
Hence it is not a linear equation in one variable.
So ‘option b’ is the answer.
Which of the following is not a linear equation in one variable? (Consider a, b and c as constants and x as variable)
Which of the following equation(s) is a linear equation in one variable?
