$x = \frac{7}{10}$ $x=7/10$ , y= $- \frac{13}{10}$ $-13/10$

Explanation:

This can be done either by elimination or substitution. Fro second equation it is x= 2+y. Substituting it for x in the first equation it would be 6(2+y) +4y=-1 which gives y= $- \frac{13}{10}$ $-13/10$ and hence x= $2 - \frac{13}{10} = \frac{7}{10}$ $2-13/10 = 7/10$
