Answer:

one solution : (-9 ; 4)

Step-by-step explanation:

hello :

the system is : 6x + 8y = -22 ....(*)

                       x + y = -5 ......(**)

by (**)    y= - x -5

put this value in (*) :  6x+8(-x-5)=-22

6x-8x-40 = -22

-2x=18

x= 18/-2

x= -9

put this value in (**) : -9+y=-5

y=4

one solution : (-9 ; 4)
