Question

Nu știu asta 51-(2660:76+x):23=28.
Pls repede va rog

Answer 1

51 -(2660 :76 + x) : 23=28

( 2660 : 76 + x) : 23=51-28

( 2660:76 + x) :23= 23

35+ x=23 x 23

35+ x=529

x=529-35

x=494

Answer 2

51- ( 2660 : 76 +x ) : 23 = 28
51- ( 35 + x ) : 23 = 28
51-( 35+x ) = 28×23
51- ( 35+x ) = 644
35+x = 644 - 51
35+x = 593
x = 593 -35
x = 558
