# Question regarding how to derive univariate Lasso closed form

In the picture we are given a lasso problem. The task is to derive equation (3) from equation (2). We do not need to show that the constraints hold for $$\mathbf{w}$$.I looked at the solution made by cardinal21 in one other question here regarding this but i could not connect the dots.I know this question is similar but if someone could help me connect the dots it would be great. Also note here x is a vector that is not normalized.
