Question

qual o valor me ajudemmm​

Answer 1

Resposta:

x = 3

y = 5/6

Explicação passo-a-passo:

6/x = 4/2

6/x * x = 4/2 * x

6 = 4x/2

6 * 2 = 4x/2 * 2

12 = 4x

12 / 4 = 4x / 4

12 /4 = x

3 = x

x = 3

6/(x + 5) = 4/(2 + y)

6/(x + 5) * (x + 5) = 4/(2 + y) * (x + 5)

6 * (2 + y) = 4/(2 + y) * (2 + y) * (x + 5)

6 (2 + y) = 4 (x + 5)

12 + 6y = 4x + 5

12 + 6y = 4 * 3 + 5

12 + 6y = 12 + 5

12 - 12 + 6y = 17 - 12

6y = 5

6y / 6 = 5/6

y = 5/6

Substituindo

12 + 6 * 5/6 = 4 * 3 + 5

12 + 5 = 12 + 5

12 = 12
