7 x X = 18939 + 3825. 70194 + X = 81376
X : 9 = 1325 dư 8
7 x X = 18939 + 3825.
7x X = 22764
X = 22764 : 7
X = 3252
Vậy X = 3252
70194 + X = 81376
X = 81376 -70194
X = 11182
Vậy X = 11182
X : 9 = 1325 dư 8
X =(1325×9) + 8
X =11925 + 8
X = 11933
Vậy X = 11933
7×X = 18939+3825
7×X = 22764
X = 22764 :7
X = 3252
70194 + X = 81376
X = 81376 – 70194
X = 11182
X : 9 = 1325 ( dư 8)
X = 1325×9+8
X = 11933
