Question

resolva a equação de 1° grau:

Answer 1

(3x - 1)/2 - (4x + 2)/4 - (2x - 4)/3 = (x - 5)/6

mmc (2,3,4,6) = 12

[(18x - 6) - (12x + 6) - (8x - 16) = (2x - 10)] / 12
(18x - 6) - (12x + 6) - (8x - 16) = (2x - 10)
18x - 6 - 12x - 6 - 8x + 16 - 2x + 10 = 0
18x - 12x - 8x - 2x - 6 - 6 + 16 + 10 = 0
-4x + 14 = 0
4x = 14
x = 14/4
x = 7/2 ou 3,5
