4 Determinaţi termenul necunoscut: a 247+x=783; e 23 536-x= 10 039; b x+318=2 467; f 873-x=243; ptozelor c 735-x=517; g x-215=772; d x-482=267; h 7815-x+737=3 511. ​

Answer 1

Răspuns:

a) 247+ X = 783

X= 783- 247

X= 536

246+536=783

b) 23536- X= 10039

X= 23536 - 10039

X= 13497

23536- 13497= 10039

c) X+ 318=2467

X= 2467- 318

X= 2149

2149+318=2467

d) 873-X= 243

X=873-243

X= 630

873- 630=243

e) 735-X= 517

X= 735-517

X= 218

735- 218= 517

f) X- 215= 772

X= 215+772

X= 987

987- 215= 517

g) X- 482=267

X= 482+267

X=749

749-482=267

h) 7815-X+737=3511

X= 7815+737=3511

8552-X= 3511

-X=8552-3511

X= 5041
