Question

Aflati numarul X:

56÷(3x-1)=4
37+2×(3x+1)=63
2009-3×(2x-1)=1005

Answer 1

56 : (3x - 1) = 4
56 = 4 * (3x - 1)
56 = 12x - 4
12x = 56 + 4
x = 60 : 12
x = 5

37 + 2 * (3x + 1) = 63
6x + 2 = 63 - 37
6x = 26 - 2
x = 24 : 6 
x = 4

2009 - 3 * (2x - 1) = 1005
- 6x + 3 = 1005 - 2009
- 6x = - 1004 - 3
x = 1007/6
x = 167 si 5/6

Answer 2

     56: (3x - 1 ) =4 
      56= 4 ( 3x -1 ) 
      56 = 12x-4
      60=12x      x= 5
