Answer 1

Respuesta:

1. 7x-5=9x+10

7x-9x=10+5

-2x=15

x= -7.5

17x+12=4x-24

17x-4x=-24-12

13x=-36

x=-36/13

x= -2.769

25x-3=11x-11

25x-11x=-11+3

14x=-8

x=4/7

-0.571

0.17x+26=0.33x+2

0.17x-0.33x=2-26

-0.16x=-24

x=-24/-0.16

x=150

0.1x-4=0.19x-7

0.1x-0.19x=-7+4

-0.09x=-3

x=-3/-0.09

33,333

2x+1=12

2x=12-1

x=11/2

x= 5.5

5(7-x)=31-x

35-5x=31-x

-5x+x=31-35

-4x=-4

x=-4/-4

x= 1

4(2-3x)=-2x-27

8-12x=-2x-27

-12x+2x=-27-8

-10x=-35

x=-35/-10

x= 3.5

6x-8=4(-2x+5)

6x-8=-8x+20

6x+8x=20+8

14x=28

x=28/14

x= 2

3(2x-2)=2(3x+9)

6x-6=6x+18

6x-6x=18+6

0=24

No tiene solución, las x se anulan

3(4x+7)=4x-25

12x+21=4x-25

12x-4x=-25-21

8x=-46

x=-46/8

x=-5.75
