$l e t u = x - z, t h e e q u a t i o n s y s t e m c a n b e$ $t r a n s f o r m e d i n t o$ $u + y = 8$ $2 u + y = 3$ $w h i c h c a n b e s o l v e d b y d e t e r m i n a n t$ $m e t h o d o r a n y o t h e r m e t h o d .$ $y = 13$ $u = - 5$ $\Rightarrow x = a n y r e a l n u m b e r$ $\Rightarrow y = 13$ $\Rightarrow z = x - u = x + 5$
