Question

41 Rezolvă prin metoda mersului invers:
x+3 300-4 260=2 040
x+6 543+3 456= 20 001
x+170+1 700 7 000
x-250-16 000= 13 750

Answer 1

x+3 300-4260=2040
x+3 300=4260+2040
x+3 300=6300
x=6300-3300
x=3000

x+6543+3456=20.0001
x+6543=20.001-3456
x+6543=16.545
x=16.545-6543
x=10.002

x-250-16000=13750
x-250=16000+13750
x-250=19750
x=19750-250
x=19500
