hình như bn viết ngược
bài giải
x + 140/x + 260=331
x nhân 2 + 140 =331-260=71
x nhân 2 =71 : 140 =0,50
x= 0,50 : 2
x=0,25
hok tốt
\(71+65\) x 4 = \(\frac{x+140}{x+260}\)
=> 71 + 260 = \(\frac{x+140}{x+260}\)
=> \(331=\frac{x+140}{x+260}\)
=> \(331.\left(x+260\right)=x+140\)
=> \(331x+86060=x+140\)
=> \(331x-x=-86060+140\)
=>330x =- 85920
=> x = -2864/11
=> \(330x=-85920\)
Tìm \(x\)
\(71+65\)x 4= \(\frac{x+140}{x}\)+ 260
\(71+65\cdot4=\frac{x+140}{x}+260\)
\(\Rightarrow71+260=\frac{x}{x}+\frac{140}{x}+260\)
\(\Rightarrow71=1+\frac{140}{x}\)
\(\Rightarrow\frac{140}{x}=70\)
\(\Rightarrow x=2\)
71+65*4=x+140 +260
x
=>71+260= x + 140 +260
x x
=>71=1+ 140
x
=> 71-1 = 140
x
=> 70=140:x
=>x=140:70=2
71 + 65 x 4 = x + 140/x + 260
331 = x/x + 140/x + 260
331 = 1 + 140/x + 260
=> 331 - 1 - 260 = 140/x
70 = 140/x
x = 140 : 70
x = 2
Tìm x biết 71 + 65 nhân 4=x+140 / x+260
tìm x
( x * 0,25 + 1999 ) * 2000 = ( 53 + 1999 ) * 2000
71 + 65 * 4 = \(\frac{x+140}{x}\) + 260
( X x 0,25+ 1999) x2000= ( 53+1999) x2000
( X x 0,25+ 1999) = ( 53+1999)x2000:2000
( X x 0,25+1999) =( 53+1999)
( X x 0,25+1999) = 2052
X+0,25 = 2052 - 1999
X+ 0,25 = 53
X = 53:0,25
X = 212
71+65 x4 = x+140/x + 260
x+140/x + 260= 71+65x4
x+140/x + 260=71 + 260
x+140/x=71
x/x +140/x=71
1+ 140/x=71
140/x=71-1
140/x=70
x=140/70

k nha linh
71 + 65 x 4 \(=\frac{x+140}{x}+260\)
Để mình giải lần nữa cho:
71 + 65 x 4 = \(\frac{x+140}{x}+260\)
71 + 260 = \(\frac{x}{x}+\frac{140}{x}+260\)
71 = \(1+\frac{140}{x}\)
\(71-1\) = \(\frac{140}{x}\)
70 = \(\frac{140}{x}\)
x = 140 : 70
x = 2
cho mk 1 cái l-i-k-e đi minh phương cái này mk giải đầu mà
tìm x: \(71+65\cdot4=\frac{x+140}{x}+260\)
\(71+65.4=\frac{x+140}{x}+260\)
\(71+260=\frac{x}{x}+\frac{140}{x}+260\)
=> \(1+\frac{140}{x}=71\)
=> \(\frac{140}{x}=71-1=70\)
=> \(\frac{140}{x}=\frac{140}{2}\)
=> x = 2
Vậy x = 2
Tìm x biết \(71+65\times4=\frac{x+140}{x+260}\)
