What is x?: 1. 8x - 28 - 2x=-10
2. 12 + 2x + 1=59
3. 4 + .25x + 3= 10
4. -2 +25x +17=-35
5. 8.6x + 4.4x - 11= 54
6. 3.3x - 26.4 -x =1.2
7. 7x - 10x + 18 +2x = -5
8. 7x+15 - 9x =5
9. 15= .5+ 3/2x +10
10. -17x - 8+ x =24

Step-by-step explanation:

1) 8x-28-2x=-10

       +28     +28

6x=18

*divide both sides by 6*

x=3

2) 12+2x+1=59

   13+2x=59

   -13       -13

       2x=46

*divide both sides by 2*

x=23

3) 4 + .25x + 3= 10

    7+.25x=10

    -7          -7

         .25x=3

*divide both sides by .25*

x=12

4)-2 +25x +17=-35

 15+25x=-35

 -15         -15

       25x=-50

*divide both sides by 25*

x=-2

5) 8.6x + 4.4x - 11= 54

  13x-11=54

       +11 +11  

  13x=65

*divide both sides by 13*

x=5

6) 3.3x - 26.4 -x =1.2

  2.3x-26.4=1.2

          +26.4  +26.4

   2.3x=27.6

*divide both sides by 2.3*

x=12

7) 7x - 10x + 18 +2x = -5

  9x-10x+18=-5

  -x+18=-5

      -18    -18

-x=-23 or x=23

8) 7x+15 - 9x =5

-2x+15=5

      -15   -15

 -2x=-10

*divide both sides by -2*

x=5

9) 15= .5+ 3/2x +10

    15=10.5+2/3x

   (2/3)4.5=3/2x(2/3)

   3=x or x=3

10) -17x - 8+ x =24

    -16x-8=24

           +8  +8

    -16x=32

*divide both sides by -16*

x=-2
