2(x+1)=2
2x + 2 = 2
2x = 2 - 2
2x = 0
x = 0/2
x = 0
3(x-2)-x=8
3x - 6 - x = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14/2
x = 7
4(-x-1)+5x-2=-2x-x
- 4x - 4 + 5x - 2 = - 2x - x
x - 6 = - 3x
x + 3x = 6
4x = 6
x = 6/4
x = 3/2
-2(x+1)=-6
- 2x - 2 = - 6
- 2x = - 6 + 2
- 2x = - 4
x = - 4/-2
x = 2
-2(x-1)=4
- 2x + 2 = 4
- 2x = 4 - 2
- 2x = 2
x = 2/-2
x = - 1
-2(-x-1)=5+1
2x + 2 = 6
2x = 6 - 2
2x = 4
x = 4/2
x = 2
3+2(4+2x)+1=20-2(2-x)
3 + 8 + 4x + 1 = 20 - 4 + 2x
12 + 4x = 16 + 2x
4x - 2x = 16 - 12
2x = 4
x = 4/2
x = 2
-2-x+4(-2x-3)-8x+1---igualamos a cero la ecuación-
- 2 - x - 8x - 12 - 8x + 1 = 0
- 14 - 17x + 1 = 0
- 13 - 17x = 0
- 17x = 13
x = 13/-17
x = - 13/17
6x=-4+x+3+1
6x = - 4 + x + 4
6x = x + 0
6x - x = 0
5x = 0
x = 0/5
x = 0
