a) X + 537 = 5250
X + 537 = 5250
X = 5250 – 537
X = 4713
b) 90532 – X = 26735
90532 – X = 26735
X = 90 532 – 26 735
X = 63 797
Tìm x:
a) x * 2 + x * 3 = 60
b) x * 15 – x * 9 = 78
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. 1337 + 13 x x = 6745 b. 142 x x – 41 x x – x = 408000
Tìm x:
a) 3/4 x X = 5/8

Tính 537 x 39 - 537 x 19
Tìm X:
a) 2/3 + x = 5/6
b) x : 5/6 = 3/10
Tìm x:
a)x+3/4=5/3
b)x-2/3=7/2
Bài 2. Tìm x:
a/ x + 456788 = 9867655 b/ x – 23345 = 9886 c/ 283476 + x = 986352
