To solve the problem, we need to apply the rule:

When two tangents intersect at a point outside the circle, they are congruent

Hence, we can write:


6x\text{ -5 = 4 + 5x}

Solving for x:


\begin{gathered} Collect\text{ like terms} \\ 6x\text{ - 5x = 4 + 5} \\ x\text{ = 9} \end{gathered}

Answer:

x = 9
