Question

Método de igualación
9x + 7y = -4
11x-13y = -48​

Answer 1

X + 3y = 6 5x + 7y = -1 3x + 4y = 8 x – 5y = 8

5x – 2y = 13 -3x + 4y = - 24 8x – 9y = -77 - 7x + 8y = 25

15x + 11y = 32 10x + 18y = - 11 4x + 5y = 5 32x – 25y = 13

-9x + 7y = 8 16x – 9y = -5 - 4x – 10y = -7 16x + 15y = 1

11x – 13y= -163

-8x + 7y = 94

espero que te ayude
