x*2 + x*3 + x*4 + x*5 + x*6 = x*9 + 9999
=> x*(2 + 3 + 4 + 5 + 6) = x*9 + 9999
=> x*20 = x*9 + 9999
=> x*20 - x*9 = 9999
=> x*11 = 9999
=> x = 909

xx2 + xx3 +xx4+ xx5 + xx6 =xx9 + 9999
xx2 + xx3 + xx4 + xx5 + xx6 -xx9 = 9999
xx*10+2+ xx*10+3+xx*10+4+xx*10+5+xx*10+6-xx*10+9 = 9999
(xx*10+xx*10+xx*10+xx*10+xx*10-xx*10) + (2+3+4+5+6-9) = 9999
xx * (10+10+10+10+10-10) + 11 = 9999
xx*(10*5-10) = 9988
sai đề rồi

X:0,1+X:0,25+X:0,5+X×4
⇒ x :0,1+ x :0,25+ X:0,5+x:0,25=2018
⇒ X:(0,1+0,25+0,5+0,25)=2018
⇒ X:1,1=2018
⇒ x=2018 x1,1=2219,8
Vậy X=2219,8

X : 0,25 + X:0,5-Xx4 =50,28
X x 4 + X x 2 - X x 4 = 50,28
X x 6 - X x 4 = 50,28
X x 2 = 50,28
X = 50,28 : 2 = 25,14

a, X x 3 x 5 = 2,7
X x 15 = 2,7
X = 2,7 : 15
X = 0,18
b, 1,2 : X x 4 = 20
X x 4 = 1,2 : 20
X x 4 = 0,06
X = 0,06 : 4
X = 0,015

dang quang thanh k tớ nhá
a) \(x.3.5=2,7\)
\(15x=2,7\)
\(x=0,18\)
vậy \(x=0,18\)
b) \(1,2:x.4=20\)
\(1,2:x=5\)
\(x=1,2:5\)
\(x=0,24\)
vậy \(x=0,24\)
\(x\) x 2 + \(x\) x 3 + \(x\) x 4 + \(x\) = 2130
\(x\) x ( 2 + 3 + 4 + 1) = 2130
\(x\) x (5 + 4 + 1) = 2130
\(x\) x (9 + 1) = 2130
\(x\) x 10 = 2130
\(x\) = 2130 : 10
\(x\) = 213
X x (1 + 2 + 3 + 4) = 2130
X x 10 = 2130
X = 2130 : 10
X = 213
Vậy X = 213
