Gọi giá trị của chữ số sau khi xóa đi số 5 là x (với \(x>0;x\in N\))

Giá trị chữ số ban đầu: \(10x+5\)

Theo bài ra ta có pt:

\(10x+5-x=1796\)

\(\Rightarrow9x=1791\)

\(\Rightarrow x=199\)

Vậy chữ số đó là \(1995\)

gọi số cần tìm là X 

vì hàng đơn vị là 5 và nếu bỏ 5 thì sẽ giảm 1796 đơn vị nên ta có :

10.X+5=X+1796

=> X=199
