\(\Rightarrow x-100=0\)( Do \(\frac{1}{30}+\frac{1}{43}+\frac{1}{95}+\frac{1}{8}\ne0\)

=> x=100

ta co(  x-10 / 30 )   -3  + ( x -14  / 43  ) -2  + ( x-5 / 95 ) -1 + ( x- 148  / 8) + 6 =0

=> (x- 10 -90 / 30  ) + ( x- 14-86  / 43 ) + ( x- 5- 95   /  95)  + ( x- 148 +48 ) =0

=> x-100 /30  +  x-100 / 43  + x- 100 / 95 +   x- 100 /  8 = 0

=> x-100 .( 1/30 + 1/43 +1/ 95 +1/ 8) =0

ma  1/30 + 1/43 + 1/ 95 + 1/8 khac 0 => x-100 =0 => x=100

h cho minh truoc da

\(\frac{x-10}{30}+\frac{x-14}{43}+\frac{x-5}{95}+\frac{x-148}{8}=0\)

\(\Rightarrow\frac{x-10}{30}-3+\frac{x-14}{43}-2+\frac{x-5}{95}-1+\frac{x-148}{8}+6=0\)

\(\Rightarrow\frac{x-100}{30}+\frac{x-100}{43}+\frac{x-100}{95}+\frac{x-100}{8}=0\)

\(\Rightarrow\left(x-100\right)\left(\frac{1}{30}+\frac{1}{43}+\frac{1}{95}+\frac{1}{8}\right)=0\)

mà \(\frac{1}{30}+\frac{1}{43}+\frac{1}{95}+\frac{1}{8}\ne0\)

=> x - 100 = 0 => x = 100

                                                       Vậy x = 100

ko biết

'''''llkj

a, => (x-10/30 - 3) + (x-14/43 - 2) + (x-5/95 - 1) + x-100/8 = 0 ( vì x-148/8 = x-100/8 + 48/8 = x-100/8 + 6 )

=> x-100/30 + x-100/43 + x-100/95 + x-100/8 = 0

=> (x-100).(1/30 + 1/43 + 1/95 + 1/8) = 0

=> x-100 = 0 ( vì 1/30+1/43+1/95+1/8 > 0 )

=> x = 100

Vậy x = 100

Tk mk nha

\(\frac{x+10}{30}+\frac{x+14}{43}+\frac{x+5}{95}+\frac{x+130}{5}=0\)

\(\Leftrightarrow\left(\frac{x+10}{30}+3\right)+\left(\frac{x+14}{43}+2\right)+\left(\frac{x+5}{95}+1\right)+\left(\frac{x+130}{5}-6\right)=0\)

\(\Leftrightarrow\frac{x+10+90}{30}+\frac{x+14+86}{43}+\frac{x+5+95}{95}+\frac{x+130-30}{5}=0\)

\(\Leftrightarrow\frac{x+100}{30}+\frac{x+100}{43}+\frac{x+100}{95}+\frac{x+100}{5}=0\)

\(\Leftrightarrow\left(x+100\right)\left(\frac{1}{30}+\frac{1}{43}+\frac{1}{95}+\frac{1}{5}\right)=0\)

Vì \(\frac{1}{30}+\frac{1}{43}+\frac{1}{95}+\frac{1}{5}\ne0\)

=> x + 100 = 0

=> x = -100

Ta có: x-10/30 + x-14/43 + x-5/95 + x-148/8 = 0

ð  X-10/30 - 3 + x-14/43 - 2 + x-5/95 - 1 + x-148/8 + 6 = 0

ð  X-10-90/30 + x-14-86/43 + x-5-95/95 + x-148+48/8 = 0

ð  X-100/30 + X-100/43 + X-100/95 + X-100/8 = 0

ð  {X-100} . {1/30 + 1/43 + 1/95 + 1/8} = 0

Vì: /30 + 1/43 + 1/95 + 1/8 khác 0

ð  X-100 = 0

ð  X = 100
