0 = 13          indefinida

x = -5

x = 2

0 = 2           indefinida

x = -12

Explicación paso a paso:

7x -9 +3x +2 = 9x +6 +x

10x -7= 10x +6

10x -10x = 6 +7

0 = 13

-4 +x +8 -6x = -2x +19

4 -5x = -2x +19

-5x +2x = 19 -4

-3x = 15

x = [tex]\frac{15}{-3}[/tex]

x = -5

2x +11 -10x = 2 +x -9

-8x +11 = -7 +x

-8x -x = -7 -11

-9x = -18

x = [tex]\frac{-18}{-9}[/tex]

x = 2

13 -5x -8 = 2x +7(1 -x)

5 -5x = 2x +7 -7x

5 -5x = -5x +7

-5x +5x = 7 -5

0 = 2

3(x +4) -2 +5x = 6x -14

3x +12 -2 +5x = 6x -14

8x +10 = 6x -14

8x -6x = -14 -10

2x = -24

x = [tex]\frac{-24}{2}[/tex]

x = -12
