2x+5-5x=-1
-3x+5=1
-3x= 1-5
-3x= -4
x= -4/ -3

5+6x=5x+2
6x-5x= 2 -5
x= -3

x+2x-1-3=x
3x-x= 1+3
2x= 4
x= 4/2
x= 2

2x+3x+4=48-8x
5x+8x= 48-4
13x= 44
x= 44/13

10-9x+2x=2-3x
-7x+3x= 2-10
-4x= -8
x= -8/ -8
x= 1

2-3x=-2x+12-3x
-3x+2x+3x= 12-2
2x= 10
x= 10/2
x= 5

7(x-5)=3(x+1)
7x-35= 3x+3
7x-3x= 3+35
4x= 38

9,5

3(x-2)=4(-x+3)
2(x+1)-(x-1)=0
3x-6= -4x+12
3x+4x=12+6
7x= 18
x= 18/7

Answer 2

2x + 5 - 5x = - 1
- 3x = - 1 - 5
 - 3x = - 6 (- 1)
   3x = 6
    x = 6/3
    x = 2

***********************
5 + 6x = 5x + 2
6x - 5x = 2 - 5
x = - 3

***************************
x + 2x - 1 - 3 = x
3x - 4 = x
3x - x = 4
2x = 4
x = 4/2
x = 2

***************************************
2x + 3x + 4 = 48 - 8x
5x + 4 = 48 - 8x
5x + 8x = 48 - 4
13x = 44
x = 44/13

****************************
10 - 9x + 2x = 2 - 3x
10 - 7x = 2 - 3x
10 - 2 = - 3x + 7x
8 = 4x
4x = 8
x = 8/4
x = 2

******************************
2 - 3x = - 2x + 12 - 3x
2 - 3x = - 2x - 3x + 12
2 = - 2x + 12
2x = 12 - 2
2x = 10
x = 10/2
x = 5

*************************
7.(x - 5) = 3.(x + 1)
7x - 35 = 3x + 3
7x - 3x = 3 + 35
4x = 38
x = 38  (:2)
      ----- 
       4   (:2)

x = 19/2

*****************************
3.(x - 2) = 4(- x + 3)
3x - 6 = - 4x + 12
3x + 4x = 12 + 6
7x = 18
x = 18/7

***************************
2.(x + 1) - (x - 1) = 0
2x + 2 - x + 1 = 0
x + 3 = 0
x = - 3
