Respuesta:
( x ; y ) = ( 6,62 ; -3,96 )
Explicación paso a paso:
[tex]\left \{ {x ={\frac{151}{27} -\frac{7}{27}y } \atop {2x - 1,2y=18}} \right.\\2(\frac{151}{27}-\frac{7}{27}y) - 1,2y =18\\y = -\frac{115}{29} \\x=\frac{151}{27} - \frac{7}{27} x(-\frac{115}{29} )\\x=\frac{192}{29}\\(x;y)=(\frac{192}{29}; -\frac{115}{29})\\(x;y)=(6,62;-3,96)[/tex]
