Explanation:

substitute y=3x-11 into 4x+5y=-17

4x+5(3x-11)=-17

4x+15x-55=-17

19x-55=-17

19x=-17+55

19x=38

x=-38/19

x=2

substitute x=2 into y=3x-11

y=3(2)-11

y=-6-11

y=-5

Answer:

4x + 5y = -17

we know if y = 3x - 11, so :

4x + 5(3x - 11) = -17

4x + 15x - 55 = -17

19x = -17 + 55

19x = 38

x = 2

y = 3x - 11

y = 3(2) - 11

y = 6 - 11

y = -5

So the answer is

x = 2

and

y = -5
