Hello there!
Answer: ⇒⇒⇒⇒⇒⇒ =3x+3
_________________________________________________________
Step-by-step explanation:
First you had to distribute parenthesis.
[tex]-(x+1)[/tex]
[tex]=-(x)-(1)[/tex]
Then apply minus-plus rules.
[tex]+(-a)=-a[/tex]
[tex]=-x-1[/tex]
[tex]=4-x-1+4x[/tex]
Simplify.
[tex]4-x-1+4x=3x+3[/tex]
[tex]4-x-1+4x[/tex]
Group like terms:
↓↓↓↓↓↓↓↓↓↓↓
[tex]=-x+4x+4-1[/tex]
Then add similar elements.
[tex]-x+4x=3x[/tex]
[tex]=3x+4-1[/tex]
Add and subtract by the number.
[tex]4-1=3[/tex]
[tex]3x+3[/tex]
[tex]=3x+3[/tex]
