Solution

$G i v e n, 2 x - 1 = 14 - x \Rightarrow 2 x + x = 14 + 1 [T r a n s p o s i n g - x t o L H S a n d - 1 t o R H S] \Rightarrow 3 x = 15 \Rightarrow x = 5 [D i v i d i n g b o t h s i d e s b y 5]$

Check:
LHS = 2x - 1 = 25 - 1 = 10 - 1 = 9
RHS = 14 - x = 14 - 5 = 9
Clearly, LHS = RHS
Hence checked!!
