Answer:

x=3, y=-4. (3, -4).

Step-by-step explanation:

3x-17=2y

5y=-4x-8

-------------

3x-2y=17

-4x-5y=8

--------------

4(3x-2y)=4(17)

3(-4x-5y)=3(8)

----------------------

12x-8y=68

-12x-15y=24

------------------

-23y=92

y=92/-23

y=-4

3x-17=2(-4)

3x-17=-8

3x=-8+17

3x=9

x=9/3

x=3
