Question

4x + 3y = 11
5x - 2y = 8
Cual es la igualación

Answer 1

Método: Comparación

{4x + 3y = 11

{5x - 2y = 8

{4x = 11 - 3y

{5x = 8 + 2y

{x = 11/4 - 3/4 × y

{x = 8/5 + 2/5 × y

11/4 - 3/4 × y = 8/5 + 2/5 × y

55 - 15y = 32 + 8y

-15y - 8y = 32 - 55

-23y = 23

y = 1

x = 8/5 + 2/5 × 1

x = 8/5 + 2/5

x = 2

(x, y) = (2, 1)
