8.75 x X + 12,5 x X =20
X x ( 8,75 + 12,5 ) = 20
X x 21,25 = 20
X = 20 : 21,25
X= \(\frac{16}{17}\)

8.75*X+12.5*X=20
\(\Rightarrow\)X*(12.5+8.75)=20
\(\Rightarrow\)X*21,25=20
\(\Rightarrow\) X=20:21.25
\(\Rightarrow\) X=16/17
8.75 x X + 1.25 x X =20
8.75 x X + 1.25x X =20
X x ( 8.75+ 1.25) = 20
X x 10 =20
X = 20 : 10
X = 2
8.75*x+1.25*x=20
\(\Rightarrow\) (8,75+1,25)*x = 20
\(\Rightarrow\) 10*x=20
\(\Rightarrow\) x = 2

13.104 : x - 8.75 = 6.88
13.104 : x - 8.75 = 6.88
<=>13.104:x=15.63
=>x=2184/2605
Vậy x=2184/2605
\(13.104:x-8.75=6.88\)
\(1352:x-600=528\)
\(1352:x=528+600\)
\(1352:x=1128\)
\(x=1352:1128\)
\(x=\dfrac{169}{141}\)

Hỏi X = ?
8,75*x+1,25*x=20
x*(8,75+1,25)=20
x*10 =20
x =20:10
x =2
Tìm X
8.75 x X + 1.25 x X =20
\(8,75\cdot x+1,25\cdot x=20\)
\(=>x\cdot\left(8,75+1,25\right)=20\)
\(=>x\cdot10=20=>x=2\)
k nha xin đó
8,75 . x + 1,25 . x = 20
x .( 8,75 + 1,25 ) = 20
x . 10 = 20
x = 20 : 10
x = 2
