Answer:

The error is in step 4

Step-by-step explanation:

[tex]\frac{x-1}{x+4} - \frac{4x-11}{x+4}[/tex]

[tex]\frac{x-1-4x-11}{x+4}[/tex]

[tex]\frac{-3x-12}{x+4}[/tex]

In order to undo division you need to multiply

[tex]\frac{-3x-12}{x+4}[/tex] × [tex]x+4[/tex]

[tex]-3x -8 = 0[/tex]

Add 8 to both sides

[tex]-3x=8[/tex]

Undo multiplication by dividing by -3

[tex]\frac{-3x}{-3} = \frac{8}{-3}[/tex]

And your answer is

[tex]x= -2.67[/tex]
