Решите уравнение: 1)2х+9,8=13,6 2)10,36-3х=5,86 3)4,2х-6=3,66 4)19,5-0,3х=15,9 5)(7-0,2х)*1,4=7,56 6)(6,1х-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
