Question

Математика: Икс+273-54=648+254 432+(808x иск)=4096: 2 (989-154)-икс=142x3

elenaagro79 · Answer

1) Х + 273-54 = 648+254
Х = (648+254)-(273-54)
Х = 902 - 219
Х = 683

2) 432+ (808*Х) = 4096:2
808*Х = (4096:2)-432
808*Х = 1616
Х =1616:808
Х = 2

3) (989-154)-Х=142*3
Х = (989-164)-(142*3)
Х = 825 - 426
Х = 399
