Answer:

a=8

Step-by-step explanation:

-5(a+3)=-55

First you times the bracket by -5

-5a-15=-55

Then you add the 15 to -55 because since the 15 is a negative on the right it has to be the opposite to the left

-5a=-40

Then you divide both sides by negative 5

-5a .     = .      -40  

---------         ----------

- 5                    -5

a= 8
