Hello!
Answer: t<-3. *The answer must have a negative sign.*
Explanation:
First, you had to do is subtract by 11 from both sides of an equation.
[tex]-3t+11-11>20-11[/tex]
[tex]-3t>9[/tex]
Multiply by -1 both sides reverse inequality.
[tex](-3t)(-1)<9(-1)[/tex]
Simplify.
[tex]3t<-9[/tex]
Then, you divide by 3 from both sides of an equation.
[tex]\frac{3t}{3}< \frac{-9}{3}[/tex]
Finally, simplify.
[tex]9/3=3[/tex]
It change positive to negative sign.
[tex]t<-3[/tex]
Hope this helps!
Thanks!
