48576 + X x 4 - 47684 = 1692
48576 + X x 4 = 1692 + 47684
48576 + X x 4 = 49376
X x 4 =49376 - 48576
X x 4 = 800
X = 800 : 4
X = 200

#)Giải :
X x 4 - 47684 = 1692 - 48576
X x 4 - 47684 = - 46884
X x 4 = - 46884 + 47684
X x 4 = 800
X = 800 : 4
X = 200
#~Will~be~Pens~#
x= (1692+47683-48576) : 4
=> x= 800:4=200
4x +892 = 1692
\(\Leftrightarrow\)4x = 1692-892
\(\Leftrightarrow\)4x = 800
\(\Leftrightarrow\)x = \(\frac{800}{4}\)
\(\Rightarrow\)x = 200
