Question

PERGUNTA SISTEMAS MAT, URGENTEEEE

Answer 1

Resposta:

x = 1/30

x = 1/30

Explicação passo-a-passo:

5x + y = 1/6

6x - y = 1/5

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

11x + 0 = 11/30

11x = 11/30

x = (11/30)/11

x = 1/30

Para

5x + y = 1/6

y = 1/6 -5x

y = 1/6 - 5/30 (simplificando)

y = 1/6 - 1/6

x = 1/30
