You don't need a computer to solve that. By the time it would take you to
program the equation you can do it in your head. It's first grade Algebra.
Simply multiple both sides by the common denominator (4 * 5) and solve.

20*B/4 - 20*B/5 = 20*8
5B - 4B = 160
B = 160

Test:
160/4 -160/5 = 40 - 32 = 8
