The first step is applying the distributive property for each product with parenthesis, so the first step is the third box.
Then, after calculating each individual product, we have:
[tex]\begin{gathered} \frac{1}{6}30x+\frac{1}{6}24-\frac{1}{7}63+\frac{1}{7}7x \\ =5x+4-9+x \end{gathered}[/tex]
So the second step is the seventh box.
Then, putting the like terms next to each other, we have:
[tex]5x+x+4-9[/tex]
So the third step is the second box.
Finally, adding the like terms, we have:
[tex]6x-5[/tex]
So the fourth step is the fifth box.
