Bài làm
[ ( x + 50 ) x 50 - 50 ] : 50 = 50
[ ( x + 50 ) x 50 - 50 ] = 50 x 50
( x + 50 ) x 50 - 50 = 2500
( x + 50 ) x 50 = 2500 + 50
( x + 50 ) x 50 = 2550
( x + 50 ) = 2550 : 50
( x + 50 ) = 2550 : 50
x + 50 = 51
x = 51 - 50
x = 1
Vậy x = 1

[ ( x + 50 ).50 - 50 ] : 50 = 50
[ ( x + 50 ).50 - 50 ] = 50.50
[ ( x + 50 ).50 - 50 ] = 2500
( x + 50 ).50 = 2500 + 50
( x + 50 ).50 = 2550
( x + 50 ) = 2550 : 50
( x + 50 ) = 51
x = 51 - 50
x = 1
