a)-24+x=13

b)x-2 i 1/5 =7,4

c)6*x=54

d)3a+1 i 3/4=2 i 1/5

e)1 i 2/3-5c=1 i 3/4

f)1/2p;1 i 3/4=8

Answer 1

a)x=13+24                                      e) -5c=1i 9/12-1 i  8/12

x=37                                                  -5c=  1/12 / :-5

 

b) x=7,4-2,2                                      c= 1/12* -1/5

x=5,2                                                c=-1/60

c)6x=54/;6                                 f) 1/2p=8-1,75

x=9                                               1/2p=6,25

d)3a=2i1/5- 1 i 3/4                        p=6,25/: 0,5

3a=2i 4/20- 1 i 15/20                    p=12,5

3a=1 i 24/20 - 1 i 15/20

3a=9/20 /;3

a=9/20  * 1/3

a=3/20
