Resposta: 12, 2, 4, 9, 6, 4, 5, 2, 1, 6, 4, 9, 7

Explicação passo a passo:

2x+3=27

2x=27-3

x=24/2

x=12

2x+3=x+5

2x-x=5-3

x=2

3x+x=16

4x=16

x=16/4

x=4

5x-9=4x

5x-4x=9

x=9

3x-7=11

3x=11+7

x=18/3

x=6

2x-9=3-x

2x+x=3+9

3x=12

x=12/3

x=4

5x=20+x

5x-x=20

4x=20

x=20/4

x=5

30=40-5x

30-40=-5x

-10=-5x

-10/5=x

x= 2

15=19-4x

15-19=-4x

-4=-4x

-4/4=x

x= 1

-7=11-3x

-7-11=-3x

-18=-3x

-18/3=x

x = 6

-4=16-5x

-4-16=-5x

-20=-5x

-20/5=x

x= 4

x=99-10x

x+10x=99

11x=99

x=99/11

x=9

7x-42=x

7x-x=42

6x=42

x=42/6

x=7
