Question 158206
I'm going to let "x" take the place of the "?"



{{{3/y = x/ky}}} Start with the given equation.



{{{(3/y)ky = x}}} Multiply both sides by {{{ky}}}.



{{{(3/cross(y))k*cross(y) = x}}} Cancel like terms.



{{{3k=x}}} Simplify



So the answer is {{{x=3k}}} which means that "3k" will take the place of the "?"
