Question

Alguem me ajuda Pfv !!!11

Answer 1

Explicação passo-a-passo:

1)4x-3x=-5+8

x=3

2)5x - 2x=25-4

3x=21

x=21/3

x=7

3)7x+2x=22+5

9x=27

x=27/9

x=3

4) 13x-2x-3=19

13x-2x= 19 +3

11x =22

x=22/11

x =2

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

5x -x - 2x = 6 - 8

2x = -2

x= -2/2

x= -1

6)7 - 9 + 3x= 31

3x = 31 -7+9

3x= 33

x=33/3 x=11

7)35x - 10 - 10x = 15 +2x - 10

35x - 10x - 2x = 15 - 10 + 10

23x =15

x= 15/23

8)6x - 17= 13x - 13 - 4

6x - 13x = -13 -4 +17

- 7x = 0

x=0

9)mmc =2

x - 162 = 210 - 2x

x + 2x = 210 +162

3x = 372

x= 124

10)mmc =3

x - 180 = 3x - 153

x - 3x = - 153 + 180

- 2x = 27

x= - 27/2

11)mmc =12

3x - 4x + 4= 1

3x - 4x = 1 -4

-x = -3

x =3

12)
