$3\mathrm{.}1\mathrm{.}7$: Proof: Two Boolean expressions are equivalent $2.$

Complete the proof that $x((\stackrel{}{x}+y)(\frac{?}{\text{b}\text{a}\text{r}}(xz)))-=x\frac{y}{b}ar(z)$ by putting each step on the left and the law that justifies the step on the right.

How to use this tool

The proof begins with the expression $x((\stackrel{}{x}+y)(\frac{?}{\text{b}\text{a}\text{r}}(xz))),$ which will be rewritten using laws of Boolean algebra. $.$
