Question

Rezolvați ecuațiile : x+25=72; 63-x=21; 125+x=715; x-1203=1751; 240+x+135=452; 525-400-x=25. Dacă vreți notați cu a) b) c).

Answer 1

47,32,590,548,77,100,

Answer 2

x+25=72
x=72-25
x=47
47+25=72/
63-x=21
x=63-21
x=42
63-42=21
125+x=715
x=715-125
x=590
125+590=715/
x-1203=1751
x=1751+1203
x=3254
3254-1203=1751/
240+x=452
x=452-240
x=212
240+212=452/
