Answer:

b=2

Step-by-step explanation:

-12+3b-1=-5-b

Combine like terms

-13 +3b = -5-b

Add b to each side

-13+3b+b = -5-b+b

-13+4b = -5

Add 13 to each side

-13+13 +4b = -5+13

4b = 8

Divide by 4

4b/4 = 8/4

b = 2

Answer: B=2


Step-by-step explanation:

                                          -12+3b-1=-5-b  Equation                                  

                                         -5+12+1=8 Adding the common number together

                                          3b+b=4b Adding the b's together

                                          4b=8 solution

                                          /4 to each side (division)

                                          b=2

When you add the numbers together it adds or subtracts from both sides so it will end up being the opposite of what it was originally ( all negative become positive. But will be on the other side)
