$\large \boxed{ \begin{array}{l} \underline{ \sf teorema \: de \: tales} \\ \\ \\ 2x - 2 = = = 2x + 6 \\ \: \: \: \: \: \: \: 2 = = = = = 3 \\ \\ (2x - 2).3 =( 2x + 6).2 \\ 6x - 6 = 4x + 12 \\ 6x - 4x = 12 + 6 \\ 2x \: = \: 18 \\ x = 18/2 \\ \boxed{x = 9} \\ \\ \\ \boxed{\boxed{\boxed{\boxed{ \large \sf{alternativa~(E)~9}}}}}\end{array}}$
