-7x + y = 29

10x + y = 16 ( sign changes)

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

-17x = 13

x = 13/-17

-7x + y = 29

- 7 (13/-17) + y = 29

5.3 + y = 29

y = 29-5.3

y = 23.7

hope it helps!

Answer:

x = -13/17

y =

Step-by-step explanation:

-7x + y = 29  ---->   y = 7x + 29

10x + y = 16 -----> 10x + 7x + 29 = 16

10x + 7x + 29 = 16

17x = -13

x = -13/17

-7x + y = 29

-7 * -13/17 + y = 29

91/17 + y = 29

y = 23 11/17
