X - 4867 = 25112500 : 25 + 23
X - 4867 = 1004500 + 23
X - 4867 = 1004523
X = 1004523 + 4867
X = 1009390
420 + 65 . 4 = ( x + 175 ) : 5 + 30
=> ( x + 175 ) : 5 + 30 = 420 + 45 . 4
=> ( x + 175 ) : 5 + 30 = 600
=> ( x + 175 ) : 5 = 600 - 30
=> ( x + 175 ) : 5 = 570
=> x + 175 = 570 . 5
=> x + 175 = 2850
=> x = 2850 - 175
=> x = 2675
