Answer:

( \frac{18}{7}\\ , \frac{92}{21} ) or x = \frac{18}{7} y =

( 2.57 , 4.18) or x = 2.57 y = 4.18

Step-by-step explanation:

Use elimination:  

Find the least common multiple between x or y in this case use -6 and 5 (make sure there are opposite signs)

11x - 6y = 2            multiply entire problem by 5                          

-8x + 5y = 3           multiply entire problem by 6

55x - 30y = 10        combine problems

<u>-48x + 30y = 18</u>

7x + 0y = 18

7x = 18 = \frac{18}{7}       Plug into one equation to find y

11(\frac{18}{7}) - 6y = 2

\frac{198}{7} - 6y = 2      

-6y = -\frac{184}{7}

y= \frac{92}{21}

Hope this helps :)
