Question

54+609:29-2 ori x=53
605 + x : 26 - 28 x 21 = 37
229 + 108 : 9 - 16 ori x = 33
x + 702 : 27 - 3 x 15 = 58
107 + x : 9 - 3 x 29 = 41
52+440 : 20 - 2 ori x = 36

Va rog sa fie puse in coloane ca sa pot intelege =] Mersi Dau 35 de puncte + raspuns castigator

Answer 1

54+609:29-2 ori x=53
54+21-2x=53
75-2x=53/-75
-2x=-22/ ori (-1)
2x=22/:2
x=11(asta a fost exercitiul 1 ti le fac in ordine)

605+x:26-28 ori 21=37
605+x:26-588=27/+588
605+x:26=625/-605
x:26=20/ ori 26
x=520

9+108:9-16x=33
229+12-16x=33
241-16x=33/-241
-16x= -208/(-1)
16x=208/:16
x=13

x+702:27-3ori 15=58
x+26-45=58/+45
x+26=103/-26
x=77

107+x:9-3 ori 29=41
107+x:9-87=41/+87
107+x:9=128/-107
x:9=21/ ori 9
x=189

52+440:20-2x=36
52+22+2x=36
74+2x=36/-74
2x=-38/:2
x= -19

succes ti le-am rezolvat pe toate!!!!
