Question

gasiti numerele naturale x pentru care se obtin propozitii adevarat . x+280=500 . x*59=59 . 16 *x=256 . x +8=14. 918-x=720. x-1234=12345

Answer 1

x=500-280
x=220

x=59:59
x=1

x=256:16
x=16

x=14-8
x=6

x=918-720
x=198

x=12345+1234
x=13579

Answer 2

REZOLVARE 

x+280=500
 x=500-280
 x=220
220+280=500

x×59=59
x=59÷59
x=1
1×59=59

16×x=256
 x=256÷16
 x=16
16×16=256

x+8=14
 x=14-8
 x=6
6+8=14

918-x=720
 x=918-720
 x=198
918-198=720

x-1234=12345
 x=1234+12345
 x=13579
13579-1234=12345
