[tex]x=-\frac{9}{7}[/tex]
Explicación paso a paso:
[tex]9-3x+2\left(3-2\right)=5\left(x+4\right)-x[/tex]
[tex]9-3x+2=5\left(x+4\right)-x[/tex]
[tex]-3x+9+2=5\left(x+4\right)-x[/tex]
[tex]-3x+11=5\left(x+4\right)-x[/tex]
[tex]-3x+11=4x+20[/tex]
[tex]-3x+11-11=4x+20-11[/tex]
[tex]-3x=4x+9[/tex]
[tex]-3x-4x=4x+9-4x[/tex]
[tex]-7x=9[/tex]
[tex]\frac{-7x}{-7}=\frac{9}{-7}[/tex]
ahí lo tienes, espero te sirva
