Question

2) Sabendo que a // b // c, determine o valor x, y, z, t
​

Answer 1

Resposta:

x1 = 6

x2 = 14

Explicação passo-a-passo:

x/(x + x + 2) = 9(9+12)

x/(2x + 2) = 9/21

x/2(x + 1) = 9/21

x = 2(x + 1).9/21

x = (x + 1).18/21

x = (x + 1).6/7

7x = 6x + 6

7x - 6x = 6

x1 = 6

6/(6 + x + 4) = 8/(8+24)

6/(x + 10) = 8/32

6/(x + 10) = 1/4

6.4 = x + 10

24 = x + 10

x = 24 - 10

x2 = 14
