Question

3. Află numerele necunoscute. a. X-24 836 = 19 685 b. x + 2 574 + 13 823 = 30 909 c. 2 050 + x - 14 521 = 8 213​

Answer 1

a. x-24836 = 19685

x = 19685 + 25836

x = 45521

b. x+2574+13823 = 30909

x + 16397 = 30909

x = 30909 - 16397

x = 14512

c. 2050 + x - 14521 = 8213

x + 2050 - 14521 = 8213

x - 12471 = 8213

x = 8213 + 12471

x = 20684
