Answer:
[tex]\huge\boxed{x<3}[/tex]
Step-by-step explanation:
Multiply -1 both sides.
[tex]\displaystyle (-13x)(-1)<-39(-1)[/tex]
Solve.
[tex]\displaystyle 13x<39[/tex]
Divide by 13 both sides.
[tex]\displaystyle\frac{13x}{13}<\frac{39}{13}[/tex]
Simplify, to find the answer.
[tex]\displaystyle 39\div13=3[/tex]
[tex]\displaystyle x<3[/tex], which is our answer.
