K cho mik với nhé Phạm Thị Thu Trang
23456+12345=12345+x
12345+x=23456+12345
12345+x=35801
x= 35801-12345=23456
Tìm x :
23456 + 12345 = 12345 + x
12345 + x = 23456 + 12345
12345 + x = 35801
x = 35801 - 12345
x = 23456
1234 + 2345 = 9876 - x
9876 - x = 1234 + 2345
9876 - x = 3579
x = 9876 - 3579
x = 6297
23456+12345=12345+x
