Hello!

Step-by-step explanation:

First, you had to do is subtract by 5 from both sides of an equation.


5-3a-5<-10-5

And then simplify.


10+5=15


-3a<-15

Next, you can also multiply by -1 from both sides of an equation. It can also used by reverse inequality.


(-3a)(-1)>(-15)(-1)

Simplify by equation.


3a>15

Then you divide by 3 from both sides of an equation.


(3a)/(3)> (15)/(3)

Finally, simplify or dividing into the groups.


15/3=5

*The answer must have a positive sign*

Final answer: →
\boxed{a>5}

Hope this helps!

Thanks!

Have a great day!

5 - 3z < -10

-5 -5 minus 5 from both sides

-3z < -15

/-3 /-3 Divide both sides by 3 and when you divide by a negative you

switch the inequality sign from < to >


z > -5
