x+8,12<9

x<9-8,12

×<0,88

0,88+8,12<9

9<9 fals pt 9=9

x-6,32>6,3

x>6,3+6,32

x>12,62

12,62-6,32>6,3

6,3>6,3 fals 6,3=6,3

8,21x<12,315

x=12,315:8,21

×=1,5

8,21×1,5<12,315

12,315<12,315 fals pt ca sunt egale

x:5,639>33,24

x=33,24×5,639

×=187,44036

187,44035:5,639>33,24

33,24>33,24 sunt egale

ex 2

x+29,3=48,15

×=48,15-29,3

×=18,85

x-32,1=17,2

×=17,2+32,1

×=49,3

8,15x=46,129

×

x=46,129:8,15

x=5,66

x:15,634=18,291

x=18,291×15,634

x=285,961494
