"The answer is:" \qquad \qquad \qquad \quad x \ = \ { 16 w } / { 5 w - 1 }.

Explanation:

"We want to solve for" \ \ x \ \ "in the equation:"

\qquad \qquad \qquad \qquad 5 w x - x \ = \ 16 w. \qquad \qquad color{blue}{"now factor" \ x \ "out on the LHS"}

\qquad \qquad \qquad \ x ( 5 w - 1 ) \ = \ 16 w \qquad \qquad \quad color{blue}{"now divide, and finish"}

\qquad \qquad \qquad \qquad \qquad \qquad \qquad x \ = \ { 16 w } / { 5 w - 1 }.

"This is our answer."
