Answer:

I am assuming you are solving for "b"

Explanation:

3b+9-16 = -56

first add the 9 and -16 to simplify

3b-7 = -56

second add 7 to both sides to leave b alone

3b = -49

lastly divide both sides by 3

b = -49/3

or you could turn it into a decimal

-16.33

Answer:

Explanation:

Get all the numbers to one side, leaving the 3b alone.

3b+9-16= -56

3b= -9+16-56

3b= -49 divide by 3

b= -49/3
