Answer 2

Resposta:

a) 2/4 = 3/x,

2x = 12

x = 12/2

x = 6

b) 4/12 = x/21

84 = 12x

x = 84/12

x = 7

c) x/14 = 9/12

12x = 126

x = 126/12

x = 10,5

d) x/3 = 8/12

12x = 24

x = 2

e) x/4 = 9/18

18x = 72

x = 72/18

x = 4

f) 10/15 = 3x + 1/5x-2

10 (5x -2) = 15 (3x + 1)

50x -20 = 45x +15

50x -45x = +20+15

5x = 35

x = 35/5

x = 7
