If the solution of the equation 2x = 4 is such that (A-1) x is a linear inequality of one variable with respect to X

If the solution of the equation 2x = 4 is such that (A-1) x is a linear inequality of one variable with respect to X

The solution of equation 2x = 4 is x = 2
By the solution of the equation 2x = 4, the linear inequality (A-1) x with respect to X is reduced
