Answer 1

Boa tarde Patricia 

x/4 - 5/3 + 10x - (x/4 + 5x/3 - 10x) 

x/4 + 10x - x/4 - 5x/3 + 10x - 5/3 

20x - 5x/3 - 5/3

60x/3 - 5x/3 - 5/3

(55x - 5)/3

b) 5x + 10 - 10(x + 3) = -5x + 13 

c) 11x + 40x - 10 + 14 = 55x + 4

d) 14x + 15/2 - 10x - 15x/2

28x/2 + 15/2 - 20x/2 - 15x/2 = -7x/2 + 15/2

e) 15x/5 - 14x/5 - 29x/5 = 28x/5

f) 2x/(2y/3) + 5x/2y/3 - 6x/2y/2 = 6x/2y + 15x/2y - 12x/2y = 13x/2y 

g) 14a/(2b/3) + 3 - 10a/(2b/2) = 11a/b + 3

h) 1/3xy + 2/3xy = 3/3xy = 1/xy
