Please solve this equation algebraically. 9(b - 4) - 7b = 5(3b -2)

And show your work.

b  = -2

Step-by-step explanation:

  Given expression:

        9(b - 4) - 7b = 5(3b -2)

Using distributive properties, open the parentheses;

     9b - 36 - 7b = 15b - 10

      2b - 36 = 15b -10

 collect like terms;

       2b - 15b  = - 10 + 36

          -13b = 26

Divide both sides by -13;

      b  = -2

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
