c. X=0
d. X= 6
e. X=10
f. X=7
Explicación paso a paso:
a. 2 -x = 6x - 12
2 + 12 = 6x + x
14 = 7x
14/7 = x
X=2
B. 1/2x + 1 = 19 - 5/2x
x +2 = 38 - 5x
x + 5x = 38 - 2
6x =36
X= 36/6
X= 6
C. x - 3 + 5x = 7 - 9x
6x - 3 = 7 - 9x
6x + 9x = 7 + 3
15x = 10
X= 10/15 = 2/3
D. x - 2x = 4x - 6x
- 1x = - 2x
-x + 2x =0
X =0

A. 2(2x +3) = - 10
4x + 6 = - 10
4x = - 10 - 6
4x = - 16
X= - 16/4
X= - 4
B. - (1 - x) = 10 (-2 + x)
-1 + x = - 20 +10x
x - 10x = - 20 + 1
- 9x = - 19
X= - 19/-9 = 19/9
C. 3(x-9)= (-9) (-x + 3)
3x - 27 = - 9 (-x + 3)
3x - 27 = + 9x - 27
3x - 9x = - 27 +27
-6x =0
X=0
D. 6 + (3 - x) + x = 2x - 3
6 + 3 - x + x = 2x - 3
9 = 2x - 3
9 + 3 = 2x
12 / 2 = x
X=6
E. 4 (3x - 2) - x = (5x + 1) 2
12x - 8 - x = 10x + 2
11x - 8 = 10x +2
11x - 10x = 2 + 8
X = 10
F. - 3 (2 - x) = (4x + 2) /2
-6 + 3x = 2x + 1
3x - 2x = 6 + 1
X = 7
