two triangles are congruentes when all sides measure the same

so first and second side are equals , just need than the third side are equal

then we match


2x-1=4x-4

and solve x


\begin{gathered} -1+4=4x-2x \\ 3=2x \\ x=(3)/(2) \end{gathered}

x is 3/2 and the third side measure 2


\begin{gathered} 2((3)/(2))-1 \\ \\ =2 \end{gathered}
