Question

Responda abaixo o calculo

Answer 1

x/3 + 8/4 - 5/2 = 4x/3 - 9/12 + x/1
x/3 - x/1 - 4x/3 = -9:3/12:3 - 8:4/4:4 + 5/2
x/3 - x/1 - 4x/3 = -3/4 - 4/1 + 5/2
mmc (3,4,2) = 12
(12:3.x) - (12:1.x) - (12:3.4x) = (12:4.(-3)) - (12:1.4)+ (12:2.5)
4x - 12x - 16x = -9 - 48 + 30
-24x = -27 .(-1)
24x = 27
x = 27/24
x = 27:3/24:3
x = 9/8
