You can put this solution on YOUR website! Let us distribute the negative sign, collect terms and solve...we get
4 - (2x-9) = -19
4 - 2x + 9 = -19
-2x + 13 = -19
-2x = -32
x = 16
You can put this solution on YOUR website! 4 - (2x-9) = -19
2x-9=-23
2x=-14
x=-7
I hope this helps
P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
