An equation and the steps to solve it are shown below:

2x - one over four of (12x + 4) = 3

Step 1: 2x + 3x + 1 = 3
Step 2: 5x + 1 = 3
Step 3: 5x + 1 - 1 = 3 - 1
Step 4: 5x = 2

In which step was the error made and why?

Step 1, because incorrect signs have been used

Step 2, because the terms have been added incorrectly

Step 3, because a number has been subtracted from both sides of the equation

I think if the equation was $$\frac{ 2x-1 }{ 4(12x+4)} = 3$$ then it would be wrong from step one but if the equation was $$2x + 3x + 1 = 3 $$
then the anwer would be No error was made
