Question

Can anybody tell me what 10b+9=29 please? :D xxx

Answer 1

10b + 9 = 29
First, bring constants to one side.
In this case, we'll have to substract 9 from both sides

Answer 2

10b + 9 = 29
10b = 29-9
10b = 20
b = 20/10
b = 2

Answer 3

10b + 9 = 29
- 9 - 9
10b = 20

Then divide by 10 both sides:
10b = 20
--- ---
10 10

b = 2
