4- x -7=-13

x + 2x= -16 + 2x

13x = -32 + 14x

30x= -40 + 31x

45x = 10 + 46 x

9x + 8 = 7x + 16

13 + 23x = 49x - 13

3(47-2x) = 5 + 12 x

4x + 11 = 12x + 43

17x - 1 = 3 + 15x

2(3x + 26) = 3(30 + 5x)

13x - 27 = 58 - 4x

Explicación paso a paso:

4- x -7=-13

-x-3=-13

-x=-13+3

-x=-10

X=10

x + 2x= -16 + 2x

3x-2x=-16

X= -16

13x = -32 + 14x

13x-14x=-32

-x=-32

X=32

30x= -40 + 31x

30x-31x=-40

-x=-40

X=40

45x = 10 + 46 x

45x-46x=10

-1x=10

X=10/-1

X=-10

9x + 8 = 7x + 16

9x-7x=16-8

2x=8

X=8/2

X=4

13 + 23x = 49x - 13

23x-49x=-13-13

-26x=-26

X=-26/-26

X=1

3(47-2x) = 5 + 12 x

141-6x=5+12x

-6x-12x=5-141

-18x=-136

X=-136/-18

X=68/9

4x + 11 = 12x + 43

4x-12,x=43-11

-8x=32

X=32/-8

X= -4

17x - 1 = 3 + 15x

17x-15x=3+1

2x=4

X=4/2

X=2

2(3x + 26) = 3(30 + 5x)

6x+52=90+15x

6x-15x=90-52

-9x=38

X=38/-9

13x - 27 = 58 - 4x

13x+4x=58+27

17x=85

X=85/17

6x -8 = 3x + 1

6x-3x=1+8

3x=9

X=9/3

X=3

7(5x + 10) = 6 (7x + 2)

35x+70=42x+12

35x-42x=12-70

-7x= -58

X= -58/-7
