Best ResponseYou've already chosen the best response.1since your triangle are similar, we can write this proportion: \[AE:AD = AB:AC\]

Best ResponseYou've already chosen the best response.1now, using your drawing, we have: \[\begin{gathered} AE = y \hfill \\ AD = AE + ED = y + 7 \hfill \\ AB = 4 \hfill \\ AC = 6 \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.1so, we can rewrite my proportion above, like below: \[y:\left( {y + 7} \right) = 4:6\] please apply the fundamental property of proportion, and solve for y

Best ResponseYou've already chosen the best response.1hint: if we apply the fundamental property of proportions, we get: \[4\left( {y + 7} \right) = 6y\] what is y?
