Answer:

x = 21/2

y = -19/2

Step-by-step explanation:

5x - 17 = 4y + 7x

5x - 7x - 4y = 17

-2x - 4y = 17

6x + 8y = - 13

-2x - 4y = 17 | ×2 |

6x + 8y = - 13 | ×1 |

-4x - 8y = 34

6x + 8y = - 13

___________+

2x = 21

x = 21/2

-2x - 4y = 17

-2(21/2) - 4y = 17

-21 - 4y = 17

-4y = 17 + 21

-4y = 38

y = -38/4

y = -19/2
