Solve the equation:

– 3b – (– 2) = 4b – 12

– 3b + 2 = 4b – 12

– 3b = 4b – 12 – 2

– 3b = 4b – 14

– 3b – 4b = – 14

– 7b = – 14

        – 14
b = ———
         – 7


b = 2   <———   solution.


I hope this helps. =)

-3(b) - (-2) - (4(b)) which is equal the number 0 
-7(b) + 14
Now, lets solve → -7 = 0 
b - 2 = 0 
Next, we add the number 2 to each of the sides of your problem 
Therefore, the result of b is 2
