Question

Va rog sa ma ajutati.

Answer 1

a)(8x-3)/4+(6x+2)5-x/2=2×[(2x-1)/10+(x+2)/5]
(8x-3)/4+(6x+2)5-x/2=(2x-1)/5+(2x+4)/5
(8x-3)/4+(6x+2)5-x/2=(2x-1+2x+4)/5
(8x-3)/4+(6x+2)5-x/2=(4x+3)/5
40x-15+24x+8-10x=16x+12
54x-7=16x+12
38x=19
x=19/38
x=1/2

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

c) 2 1/3 -4x=x/3+0,(6)
  7/3 -4x=x/3+2/3
5/3-4x=x/3
5-12x=x
13x=5
x=5/13

d) 3(x- 1/3) =2(x +3/2)
3x-1=2x+3
x=4
