Simplifying
20b + -16 = 0

Reorder the terms:
-16 + 20b = 0

Solving
-16 + 20b = 0

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '16' to each side of the equation.
-16 + 16 + 20b = 0 + 16

Combine like terms: -16 + 16 = 0
0 + 20b = 0 + 16
20b = 0 + 16

Combine like terms: 0 + 16 = 16
20b = 16

Divide each side by '20'.
b = 0.8

Simplifying
b = 0.8
