Solution
Your input: find the constant of variation $$$k$$$ given $$$y=k x$$$, $$$y=5$$$ when $$$x=2$$$ and find $$$x$$$ when $$$y=3$$$.
We have that $$$y=k x$$$.
Plug in the given values to find $$$k$$$: $$$5=k \cdot 2^{1}$$$.
Solving this equation, we obtain that $$$k=\frac{5}{2}$$$.
Now find $$$x$$$.
Plug in the given values and found $$$k$$$ to find $$$x$$$: $$$3=\frac{5 x^{1}}{2}$$$.
From this equation, we have that $$$x=\frac{6}{5}$$$.
Answer: the constant of variation is $$$k=\frac{5}{2}$$$, $$$x=\frac{6}{5}$$$.
