Question

What is the value of b? 11 + 4b = 8b - 13

Answer 1

11 + 4b = 8b - 13

11 + 4b - 8b +13 = 0

4b = 24

b = 6

Answer 2

Move like terms together and remember to change the signs when moving across the equals sign.
11➕13----8b-4b
Now simplify
24---4b
Divide both sides by 4 to get 1b

6---b
