........................................................................................................................ giúp mình nha các bạn!
a) x = 9867655 - 456788
x = 9410867
b) x = 9886 + 23345
x = 33231
c) x = 986352 - 283476
x = 702876
d) y =44772 : 123
y = 364
e) a = 2345 x 637
a = 1493765
g) x = 212552 : 326
x = 652

h/ 40000 – x =3876
x = 40000 – 3876
x = 36124
i/ (x + 1233) – 1978 = 9876
x + 1233 = 9876 + 1978
x + 1233 = 11854
k/ x : 2 : 3 = 138
x : 2 = 138 x 3
x : 2 =414
x = 414 x 2
x = 828
