Answer 1

g)

[3(x - 1) - 2x]/5 = 5(x - 3)/6

(3x - 3 - 2x)/5 = (5x - 15)/6

(x - 3)/5 = (5x - 15)/6

6(x - 3) = 5(5x - 15)

6x - 18 = 25x - 75

75 - 18 = 25x - 6x

57 = 19x

x = 57/19

x = 3

h)

(2x + 5)/3x = 1/4

4(2x + 5) = 1(3x)

8x + 20 = 3x

8x - 3x = - 20

5x = - 20

x = - 20/5

x = - 4

Bons estudos!
