Answer: (11, 13)

Step-by-step explanation:

[tex]5x + 5y = -10\\6x + 5y -1[/tex]

o eliminate a variable use linear combinations method to add equations together- but multiply one equation by -1 first, so a variable will eliminate

[tex]-5x - 5y = 10\\6x + 56 =1\\\\x+ 0y=11\\x=11[/tex]

The put 11 in for X and solve for y

[tex]5(11) + 5y = -10\\55 + 5y = -10\\5y = -65\\y=13[/tex]
