Hello!

Answer:

a=-4

*The answer must have a negative sign.*

Explanation:

Distributive property: a(b+c)=ab+ac

First, you subtract by 5 from both sides of an equation.


3a+5-5=a-3-5

Then, simplify.


3a=a-8

Next, you subtract by a from both sides of an equation.


3a-a=a-8-a

Simplify.


2a=-8

Then you can also divide by 2 from both sides of an equation.


(2a)/(2)=(-8)/(2)

And finally, simplify and solve. You can also divide by the numbers.


8/2=4


a=-4

Hope this helps!

Thanks!

Have a great day!
