Alright, I kind of zoned out in class the other day, and I can't remember the method to solve for x in this equation.

3 + 2[4x − 3(5 − x)] = 3(x − 20)

The answer to this question is x = -3 but i can't for the life of me figure out the right steps in order to get there, been trying for hours haha.

If anyone can explain to me the steps in detail how to show my work for this type of question it would be much appreciated!
