Answer 2

Respuesta:

y = 1

x = - 1

Explicación paso a paso:

2x + 3y = 1

4x - 5y = - 9

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

- 2 (2x + 3y = 1)

4x - 5y = - 9

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

- 4x - 6y = - 2

4x - 5y = - 9

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

- 11y = - 11

y = - 11 / - 11

y = 1

2x + 3y = 1

2x + 3 (1) = 1

2x + 3 = 1

2x = 1 - 3

2x = - 2

x = - 2 / 2

x = - 1
