Solving
3ab + bA = 0

Solving for variable 'a'.

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

Add '-1bA' to each side of the equation.
3ab + bA + -1bA = 0 + -1bA

Combine like terms: bA + -1bA = 0
3ab + 0 = 0 + -1bA
3ab = 0 + -1bA
Remove the zero:
3ab = -1bA

Divide each side by '3b'.
a = -0.3333333333A

Simplifying
a = -0.3333333333A
