Question

2X - 3Y = 14 3X +2Y = -18

Answer 1

Respuesta:

Explicación paso a paso:

2x -3y = 14 (-3)

3x + 2y =-18 ( 2)

-6x + 9y = -42

6x + 4y = -36

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

13 y = - 78

y = -78/13

y = -6

Y = -6

-6x + 9 × -6 = -42

- 6x - 54 = - 42

-6x = -42 + 54

x = 12 ÷- 6

x = - 2

X= -2

Comprobante

-6 × -2 + 9 × -6 = -42

6 ×-2 + 4 × -6 = -36
