64155:x-354=633
64155:x =633+354
64155:x =
x =64155:987
vậy x=65
hok tốt
64155 : x - 254 = 633
64155 : x = 633 + 254
64155 : x = 987
x = 64155 : 887
x = 65
64155 : x=633+354
64155 : x=987
x=64155:987
x=65
64 155 : x - 354 = 633
64 155 : x = 633 + 354
64 155 : x = 987
x = 64 155 : 987 = 65
Ta có:
64 155 : x - 354 = 633
64 155 : x = 633 + 354
64 155 : x = 987
x = 64 155 : 987
x = 65
64155 : x - 354 = 633
64155 : x = 633 + 354
64155 : x = 987
x = 64155 : 987 = 65
Học tốt!
64155 : x - 354 = 633
=> 64155 : x = 987
=> x = 65
