Question

Metoda mersului invers:
(X-1475):25•103+8008:143-71=1530

Answer 1

(X-1475):25•103+8008:143-71=1530

(x-1475):25*103+56=1530+71=1601

(x-1475):25*103=1601-56=1545

(x-1475):25=1545:103=15

x-1475=15*25=375

x=375+1475=1850

x=1850

Answer 2

Răspuns

Explicație pas cu pas:

(X - 1 475 ) : 25 • 103 + 8 008 : 143 - 71 = 1 530

(X - 1 475 ) : 25 • 103 + 56 = 1 530 + 71

(X - 1 475 ) : 25 • 103  = 1 601 - 56

(X - 1 475 ) : 25 • 103 = 1 545

(X - 1 475 ) : 25 = 1 545 : 103

(X - 1 475 ) : 25 = 15

X - 1 475 = 15 • 25

X - 1 475 = 375

X = 375 + 1 475

X = 1 850 →  numarul, aflat prin metoda mersului invers
