so if i substitute that into the second equation i will have \[\huge \frac{\frac{bx}{y}}{2b} = \frac{3xc}{y}\] you following?

lgbasalloteBest ResponseYou've already chosen the best response.2
so again i simplify \[\huge \frac{bx}{2by} = \frac{3xc}{y}\] do you see the next step now?

\[\huge \frac{\frac{bx}{y}}{2b} \implies \frac{bx}{y} \times \frac{1}{2b} \implies \frac{bx}{2by}\] see it now?
