(3x-2)*2/3+3/2 = 3 : 6/5
(3x-2)*2/3+3/2 = 3*5/6
(3x-2)*2/3+3/2 = 5/2
(3x-2)*2/3 = 5/2-3/2
(3x-2)*2/3 = 2/2
3x-2 = 2/2:2/3
3x-2 = 2/2*3/2
3x-2 = 3/2
3x= 3/2 +2 amplifici pe 2 cu 2
3x = 3/2+4/4
3x=7/4
x= 7/4*1/3
x=7/12
Răspuns:
Explicație pas cu pas:
[(3x-2)×2/3+3/2]×6/5=3
(3x·2/3-4/3+3/2)·6/5=3
3x·2/3-4/3+3/2=15/6
2x-4/3+3/2=5/2 2x-4/3=5/2-3/2 2x-4/3=1
2x=1+4/3 2x=7/3 x=7/6
