6x - 4y = - 5

4x + 5y = - 11

x = - 1.5, y = - 1

Step-by-step explanation:

6x = - 5+4y

x = (-5+4y) / 6

4 ((-5+4y) / 6) + 5y = - 11

4 (-5+4y) + 5*6y = - 11*6

-20+16y+30y = - 66

16y + 30y = - 66+20 = - 46

y (16 + 30) = - 46

y = - 46 / (16 + 30)

y = - 46 / 46

y = - 1

x = (-5+4 (-1)) / 6

x = (-5-4) / 6

x = - 9 / 6

x = - 1.5
