Question

(X-1475):25×103+8008:143-71=1530

Answer 1

(x - 1475) : 25 · 103 + 8008 : 143 - 71 = 1530

(x - 1475) : 25 · 103 + 56 - 71 = 1530 /+71

(x - 1475) : 25 · 103 + 56 = 1601 /-56

(x - 1475) : 25 · 103 = 1545 /:103

(x - 1475) : 25 = 15 /·25

x - 1475 = 375 /+1475

x = 1850.

Answer 2

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

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

( X - 1 475 ) : 25 × 103 = 1 530 + 71 - 56 → metoda mersului invers

( X - 1 475 ) : 25 × 103 = 1601 - 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
