How many solutions are there to the equation below 4x - 9(x plus 1) 20 - 5x?

To solve the equation ( 4x - 9(x + 1) = 20 - 5x ), first simplify both sides. Expanding the left side gives ( 4x - 9x - 9 = 20 - 5x ), which simplifies to ( -5x - 9 = 20 - 5x ). Adding ( 5x ) to both sides results in ( -9 = 20 ), which is a contradiction. Thus, there are no solutions to the equation.
