39 = 1  1/10b
----------
Simplify and flip
39 = 13/10b
13/10b = 39
---------------------
Multiply each side by 10/13
10/13 * 13/10b = 10/13 * 30
b = 30

First make the equation 39=1-((3/10)*b / / - 1-((3/10)*b. Next it should look like (3/10)*b-1+39=0. After that do 3/10*b+38=0//-38. Then do 3/10*b= -38// : 3/10. Your answer after simplifying b= -38/3/10 should be b= -380/3.
