Giúp tôi giải toán X nâng cao nhé các bạn. Ai giải đúng 4 câu này thì tôi hậu tạ
X-1046+1586=5473
X- 2632=5473
X = 5473-2632
X =2841
1475+X=7684+1542
1475+X=9226
X = 9226-1475
X = 7751
5896-X+278=202
X+278=5896-202
X+278=5694
X=5694-278
X=5416
X-845=7981-6857
X-845=1124
X=1124+845
X=1969
x - 1046 + 1586 = 5473
x- 1046 = 5473 - 1586
x - 1046 = 3887
x= 3887 + 1046
x = 4933
1475 + x = 7684 + 1542
1475 + x = 9226
x = 9226 - 1475
x = 7751
5896 - x + 278 = 202
x + 278 = 5896 - 202
x + 278 = 5694
x = 5694 - 278
x = 5416
x - 845 = 7981 - 6857
x - 845 = 1124
x = 1124 + 845
x = 1969
