Answer:

no solution

Explanation:


-5x+4y=39


5x-4y=25

To do this, set up the equations in Slope-Intercept Form.

What is Slope-Intercept Form?

Slope-intercept Form is y = mx + b where m is the slope and b is the y-intercept

_______________________________________________________


-5x+4y=39

Step 1. Solve for y by dividing everything by 4


y=(5)/(4) x+(39)/(4)

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


5x-4y=25

Step 1. Same thing, divide everything by 4


y=(5)/(4) x-(25)/(4)

Now, we're ready to solve the system!


(5)/(4) x+(39)/(4)=(5)/(4) x-(25)/(4)

Subtract
(5)/(4) x from both sides.


(39)/(4) \\eq (-25)/(4)

Since the y values don't match then therefore the x values can't match either, thus, there is no solution.
