Question

[(3x-2)×2/3+3/2]×6/5=3

Answer 1

(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

Answer 2

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
