Rezolvati ecuatiile in multimea numerelor intregi​

Answer 1

Explicație pas cu pas:

a)7x+14=-56

7x=-56-14

7x=-70

x=-70:7

x=-10

b) 11x-33=77

11x=77+33

11x=110

x=110:11

x=10

c)19x+1=172

19x=172-1

19x=171

x=171:19

x=9

d)-51x+24=177

-51x=177-24

-51x=153

-x=153:51

-x=3

x=3

e)6x+2=-46

6x=-46-2

6x=-48

x=-48:6

x=8

f)-7x-5=5

-7x=-5+5

-7x=o

x=0

g)-9x-3=-102

-9x=-102+3

-21x=295-43

-21x=252

x=252:21

x=12

i)15x+24=-81

15x=-81-24

15x=105

x=105:15

x=7

j)6x-2=-11

6x=-11+2

6x=-9

x=-9:6

x=-1,5
