Hướng dẫn giải:
a.
x : 14 = 301
x = 301 x 14
x = 4214
b.
x : 103 = 101
x = 101 x 103
x = 10403
c.
x : 11 = 32
x = 32 x 11
x = 352
( 5+x)+(7+x)+(9+x)+...+(101+x)+(103+x)=2850
a,970-x+x+x+...+x=1874(có 10 chữ số x)
b,(5+x)+(7+x)+(9+x)+...+(101+x)+(103+x)=2850
a,970-x+x+x+...+x=1874(có 10 chữ số x )
b,(5+x)+(7+x)+(9+x)+...+(101+x)+(103+x)=2850
Tìm x:
a) x * 2 + x * 3 = 60
b) x * 15 – x * 9 = 78
Tìm x:
a. 1337 + 13 x x = 6745 b. 142 x x – 41 x x – x = 408000
Tìm x:
a. 246 : x + 34 : x = 5 b. 360 : x – 126 : x = 6
Bài 4:Tìm x:
a) 243 x x =76545 b) 97328 : x = 316
Tìm x:
a) 3/4 x X = 5/8

Bài 2. Tìm x:
a/ x + 456788 = 9867655 b/ x – 23345 = 9886 c/ 283476 + x = 986352
