Answer 1

1.  0.7*10*х=4*0.63

7x=2,52

x=2,25:7

x=0,36

 

2.  х*2.5*40=2.3-1.26

100x=1,04

x=1,04:100

x=0,0104

 

3.   0.004*10=15.3х-7.3х

8x=0,04

x=0,04:8

x=0,005

 

4.0.3/150=0.6х-0.55x+3.95х

4x=0,002

x=0,002:4

x=0,0005

 

5.  1.1*2.1х=0.2х+1.8х-0.35х

2,31x=1,65x

2,31x-1,65x=0

0,66x=0

x=0

 

6.  2.5х+6.08х+х=479/10

9,58x=47,9

x=47,9:9,58

x=5

 

7.   0.3х+х-0.15х=16.1*0.01

1,15x=0,161

x=0,161:1,15

x=0,14

 

8.   х-0.25х-0.3х=135/1000

0,45x=0,135

x=0,134:0,45

x=0,3

 

9.   5х-4.3х+1.3х=0.0003/0.01

2x=0,03

x=0,03:2

x=0,015

 

10.   1.75х+50-0.3=84.7 

1,75x=84,7-50+0,3

1,75x=35

x=35:1,75

x=20
