Answer 1

Răspuns:

a)5.3x+1.2=25.209

5.3x=25.209-1.2

5.3x=24.009

x=24.009÷5.3

x=4.53

b)1.5x-7.43=4.12

1.5x=4.12+7.43

1.5x=11.55

x=11.55÷1.5

x=7.7

c)3x+18.23=107.33

3x=107.33-18.23

3x=89.1

x=89.1÷3

x=29.7

d)1.898-4x=0.458

-4x=0.458-1.898

-4x= -1.44

x= -1.44÷(-4)

x=0.36

e)2x+5.17=8.49

2x=8.49-5.17

2x=3.32

x=3.32÷2

x=1.66

f)0.3x-4.29=10.83

0.3x=10.83+4.29

0.3x=15.12

x=15.12÷0.3

x=50.4

g)2.18-0.5x=1.45

-0.5x=1.45-2.18

-0.5x= -0.73

x= -0.73÷(-0.5)

x=1.46

e)19.534÷0.2-0.01x=18.54

97,67-0.01x=18.54

-0.01x=18.54-97.67

-0.01x= -79.13

x= -79.13÷(-0.01)

x=7913
