If two angle of a triangle are congruent , then sides of opposite those angle are congruent Then in triangle ABC is:

$\begin{gathered} AC=AB \\ 2x+7=4x-7 \\ 4x-2x=7+7 \\ 2x=14 \\ x=(14)/(2) \\ x=7 \end{gathered}$

So the large side is BC:

$\begin{gathered} BC=4x \\ BC=4*7 \\ BC=28 \end{gathered}$
