Question

-5x + 7y = -1
-3x + 4y = -24

AYUDA PLIS ES PARA AHORA​

Answer 1

Método: Sustitución

{-5x + 7y = -1

{-3x + 4y = -24

{-5x + 7y = -1

{x = 8 + 4/3 × y

Para y...

-5(8 + 4/3 × y) + 7y = -1

-40 - 20/3 × y + 7y = -1

-40 + 1/3 × y = -1

-120 + y = -1

y = -3 + 120

y = 117

Para x...

x = 8 + 4/3 × 117

x = 8 + 4 × 39

x = 8 + 156

x = 164

(x, y) = (164, 117)
