Solving
0.5a + 0.1b = 0

Solving for variable 'a'.

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

Add '-0.1b' to each side of the equation.
0.5a + 0.1b + -0.1b = 0 + -0.1b

Combine like terms: 0.1b + -0.1b = 0.0
0.5a + 0.0 = 0 + -0.1b
0.5a = 0 + -0.1b
Remove the zero:
0.5a = -0.1b

Divide each side by '0.5'.
a = -0.2b

Simplifying
a = -0.2b
