Odpowiedź:

6+x=2

x = 2 - 6

x = -4

x:3=9

x = 9 x 3

x = 27

1/3•x=12

x= 12/ 1/3

x = 12 x 3

x = 36

3•(x-5)=9

3x - 15 = 9

3x = 15 + 9

3x = 24/3

x = 8

1•x+6=0

1x = - 6

x = -6

3,7+x=4

x = 4 - 3,7

x = 0,3

4•(x-2)=0

4x - 8 = 0

4x = 8//4

x = 2

x/2=9

x = 18

2•x=8

x = 4

(-10)=5•x

x = -10 - 5

x = -15

x-7=9

x = 9 + 7

x = 16

3•x-10=5

3x = 5 + 10

3 x = 15//3

x = 5

3•x-5=9

3x = 9+5

3x = 14//3

x = 3/14

6•x+19=5

6x = 5-19

6x = -14//6

x = -7/3

4•x+12=40

4x = 40 - 12

4x = 28//4

x = 7

7•x-5=4

7x = 4 + 5

7x = 9 //7

x = 7/9
