We can write this as an inequality:
[tex]1 + 3x \ \textless \ x - 5[/tex]
We can deal with this very easily:
[tex]1 + 2x \ \textless \ -5[/tex]
[tex]2x \ \textless \ -6[/tex]
[tex]x \ \textless \ -3[/tex]
I solved it for you, I cannot graph due to Brainly not supporting it. Sorry, and hope this helps!
