Question

resposta com contas

Answer 1

a) (x/6) = (1/4)-(1/12) 
(x/6) = (-1/12)
x= -6/12 
x= -1/2 

b) (x/6) = (1/2) + (1/3) 
(x/6) = (5/6 )
x = 5 

c) x + x/3  = 8 
4x = 24 
x = 6 

d) (x/3) - (x/4) = 1 
(4x-3x)/12 = 1 
x/12  = 1
x = 12 

Answer 2

A) X/6 + 1/12 = 1/4       MMC = 12
2X + 1 = 3
2X = 2
X = 1

B) X/6 - 1/3 = 1/2      MMC = 6
X - 2 = 3
X = 5

C)X + X/3 = 8       MMC = 3
3X + X = 24
4X = 24
X = 24 / 4
X = 6

D) X/3 - 1 = X / 4        MMC = 12
4X - 12 = 3X
4X - 3X = 12
X = 12
