Question

Me ajudem a resolva essas equação apenas as letras A,B E D

Answer 1

A
1/2(2X/3 + 1/4) = 1/3( 1/2 - X)
( 2X/6 + 1/8) = ( 1/6 - X/3 )
MMC  24
8X + 3 = 4 - 8X
8X + 8X = 4 - 3
16X = 1
X = 1/16 ****
B
3( X - 2)/2  - ( X - 3)/4 =( 2X - 1)/1
(3X - 6 )/2 - 1( X - 3)/4 = ( 2X - 1)/1
MMC = 4
2( 3X - 6) - 1( X - 3) = 4 ( 2X - 1)
6X - 12 - X + 3 = 8X - 4
5X - 9 - 8X + 4 = 0
-3X - 5 = 0
-3X = +5
3X = -5
X = -5/3 *****
D
5/1 + 1/2 ( X/4 + 4/1 ) = 1/4( 2X - 5)
5/1 + ( X/8 + 4/2 ) =( 2X/4 - 5/4 )
MMC =  8
40 + ( X + 16 ) = 4X - 10 
X - 4X = -10 - 40 - 16
-3X = - 66
3X = 66
X = 66/3 = 22 ****

E
4/1 - 4/5 ( X/1 + 1/2) = 6/1
4/1 - ( 4X/5 + 4/10 ) = 6/1
MMC  10
40 - 8X + 4 = 60
-8X = 60 - 40 - 4
-8X = 16
8X = -16
X = -16/8 = -2 ****
