How do I do this? solve 2A/3 = 8 + 4A for A

Solve the following equation for A : 2A/3 = 8 + 4A

I don't remember the formula to solve this, it's been 6 years since I've had a math class and I've forgotten. I just need some steps and examples. Thanks.

2A/3 x 3 = 8 X 3 + 4A x 3
2A = 8 x 3 + 4A x 3
2A = 24 + 12A
2A - 12A = 24 + 12A - 12A
2A - 12A = 24
2A + -12A = 24
-10A = 24
-10A/-10 = 24/-10
A= 24/-10
A = -2.4
