a) x - 306 = 504
x = 504 + 306
x = 810
b) x + 254 = 680
x = 680 - 254
x = 426
a) x - 306 = 504
x = 504 + 306
x = 810
b) x + 254 = 680
x = 680 - 254
x = 426
Tìm x: x - 306 = 504
Tìm x: x + 254 = 680
Tìm x.
254 + x = 680
Bài 4 tìm x
a ) X 36 = 972
b ) ( X - 47 ) x 21 = 840
c ) X x 22 + X x 50 = 504
d ) 254 : x = 14 ( dư 16 )
e ) 729 : X = 81
f ) y x 15 + y x 13 = 560 x 45
giúp em với !
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:
