Answer
$x=3$
Work Step by Step
In the given equation (item $
23
$), $
\dfrac{5}{x}=\dfrac{20}{12}
,$ let
\begin{array}{l}\require{cancel}y_1
=\dfrac{5}{x}
,\\\\y_2=
\dfrac{20}{12}.\end{array}
Using a graphing calculator, the red graph is the graph of $y_1$ and the blue graph is the graph of $y_2.$ The solution is the $x$-coordinate of the point of intersection/s of the two graphs. Hence, based on the graph, the solution is $
x=3
.$ This confirms the algebraic solution of the said item.
