Question

-2x -9y=-25
2x + 9y =20

find x and y value

Answer 1

There is no solution because the slopes are the same

Answer 2

no solution

Explanation:

given the system of equations

- 2x - 9y = - 25 → (1)

2x + 9y = 20 → (2)

add the 2 equations term by term

(2x - 2x) + (9y - 9y) = 20 - 25 , that is

0 + 0 = - 5

0 = - 5 ← not possible

This situation means the system has no solution
