Answer:

Fourth option

Explanation:

If you dont have a graphing calculator, we can solve this system using elimination. If we subtract the two linesr functions, we get


(3x - 8y = 29) - (3x + y = - 2) = - 9y = 31

So our new equation is


- 9y = 31


y = - (31)/(9)

Now since we know what y is, we plug this in back into the equation and solve for x.


3x - 8( ( - 31)/(9) ) = 29


3x + (248)/(9) = 29


3x = (13)/(9)


x = (13)/(27)

The answer choice that resembles this mostly is the fourth option.
