Is 3 / x = 4 a linear equation of one variable? It can be reduced to 4x = 3

Is 3 / x = 4 a linear equation of one variable? It can be reduced to 4x = 3

3 / x = 4 is not a linear equation of one variable, but a fractional equation
Although it can be reduced to 4x = 3, their value ranges are different
In 3 / x = 4, X ≠ 0, in 4x = 3, X ∈ R
