Answer 1

Ответ:

Пошаговое объяснение:

1) 6x - 19 =x+11

6x - x = 11 + 19

5x = 30

x = 30 : 5

x = 6

2) 3x=28+x

3x - x = 28

2x = 28

x = 28 : 2

x = 14

3) 6x+12=4x+16

6x - 4x = 16 - 12

2x = 4

x = 4 : 2

x = 2

Answer 2

6x - 19 =x+11  

6x - x = 11 + 19  

5x = 30  

x = 6

3x=28+x  

3x - x = 28  

2x = 28  

x = 14

6x+12=4x+16  

6x - 4x = 16 - 12  

2x = 4    

x = 2
