tìm x a) x x 15 + x x 13 = 560 x 45 b) x x 125 - x x 73 = 1196
Giúp mình với^^a)x*15+ x*13=560*45
b)x*125-x*73=1196
a) x . 15 + x . 13 = 560 . 45
x ( 15 + 13 ) = 25 200
x . 28 = 25 200
x = 25 200 : 28
x = 900
b) x . 125 - x . 73 = 1196
x ( 125 - 73 ) = 1196
x . 52 = 1196
x = 1196 : 52
x = 23
X x 15 + X x 13 = 560 x 45
X x [ 15+13] = 25200
x * 18 = 25200
x = 25200 : 18
x = 1400
b, x*125-x*73=1196
x * [125-73]=1196
x*52=1196
x = 1196 : 52
x = 23
Tìm x
a) X x 15 + X x 13 = 560 x 45
( X + X x 2 ) : 34 = 504
360 : X - 126 = X = 6
58 x X - 934 = 6722
14968 - X x 5 = 4968
b) X x 125 - X x 73 = 1196
246 : X = 34 : X = 5
2005 + X x 34 = 5337
X : 1234 = 127 ( dư 360 )
bạn ghi cái j thế ?

Tìm x a X x 15 X x 13 560x45b X x 125 x X 73 1196Nhanh tay mình tick
Tìm x,biết : x-125= -85
Tìm X :
A) 846 : X x 2 = 9
B) X x 15 + X x 13 = 560 x 45
a, 846 : X x 2 = 9
X x 2 = 846 : 9
X x 2 = 94
X = 94 : 2
X = 47
b, X x 15 + X x 13 = 560 x 45
X x 15 + X x 13 = 25200
X x ( 15 + 13 ) = 25200
X x 28 = 25200
X = 25200 : 28
X = 900
Tìm x:
a)X x 15+X x 13=560x45
b)X x 125-x X 73=1196
Nhanh tay mình tick!!!!!
a) X x 15 + X x 13 = 560 x 45
X x ( 15 + 13 ) = 25200
X x 28 = 25200
X = 25200 : 28
X = 900
b tương tự
. Tìm x:
a./ X x 15 + X x 13 = 560 x 45 b./ (X x 4 + X x 6 ) : 25 = 42
. Tìm x:
a./ X x 15 + X x 13 = 560 x 45 b./ (X x 4 + X x 6 ) : 25 = 42
a) \(x\times15+x\times13=560\times45\)
\(\Rightarrow x\times\left(15+13\right)=25200\)
\(\Rightarrow x\times28=25200\)
\(\Rightarrow x=25200:28\)
\(\Rightarrow x=900\)
bài 6 : Tìm y
a) y x 15 + y x 13 = 560 x 45 b) y x 345 - y x 44 - y = 123600
a) \(y\times15+y\times13=560\times45\)
\(y\times\left(15+13\right)=25200\)
\(y\times28=25200\)
\(y=25200:28\)
\(y=900\)
b) \(y\times345-y\times44-y=123600\)
\(y\times\left(345-44-1\right)=123600\)
\(y\times300=123600\)
\(y=123600:300\)
\(y=412\)
