Решите уравнение: 1) 2 х+9,8=13,6

2) 10,36-3 х=5,86

3) 4,2 х-6=3,66

4) 19,5-0,3 х=15,9

5) (7-0,2 х) * 1,4=7,56

6) (6,1 х-13,2) : 1,7=3

1) 2x9.8=13.6

2x=13.6-9.8

2x=3.8

x=3.8/2

x=1.9

2) 10.36-3x=5.86

10.36-5.86=3x

4.5=3x

x=4.5/3

x=1.5

3) 4.2x-6=3.66

4.2x=3.66+6

4.2x=9.66

x=9.66/4.2

x=2.3

4) 19.5-0.3x=15.9

19.5-15.9=0.3x

3.6=0.3x

x=3.6/0.3

x=12

5) (7-0.2x) * 1.4=7.56

7-0.2x=7.56/1.4

7-0.2x=5.4

7-5.4=0.2x

1.6=0.2x

x=1.6/0.2

x=8

6) (6.1x-13.2) / 1.7=3

6.1x-13.2=3*1.7

6.1x-13.2=5.1

6.1x=5.1+13.2

6.1x=18.3

x=18.3/6.1

x=3
