Is 3g(x) x a linear equation?

The expression (3g(x) = x) can be considered a linear equation if (g(x)) is a linear function. A linear equation has the form (y = mx + b), where (m) and (b) are constants. If (g(x)) is indeed linear, then (3g(x)) will also be linear, making the equation (3g(x) = x) a valid linear equation. However, if (g(x)) is nonlinear, then the equation would not be linear.
