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
a) Tìm x thỏa mãn: \(\frac{x-10}{30}+\frac{x-14}{43}+\frac{x-5}{95}+\frac{x-148}{8}=0\)
b) Tìm số nguyên x,y biết: 42 - 3|y-3| = 4(2012 - x)4
Tìm x : \(\frac{x-10}{30}+\frac{x-14}{43}+\frac{x-5}{95}+\frac{x-148}{8}=0\)0
Tìm x biết: \(\frac{x-10}{30}+\frac{x-14}{43}+\frac{x-5}{95}+\frac{x-148}{8}=0\)
\(\frac{x-10}{30}+\frac{x-14}{43}+\frac{x-5}{95}+\frac{x-148}{8}=0\)
Tìm x thuộc Q biết:
\(\frac{x+10}{30}+\frac{x+14}{43}+\frac{x+5}{95}+\)\(\frac{x+130}{5}=0\)
2,Tìm x biết: \(\frac{X-10}{30}\) + \(\frac{X-14}{43}\) + \(\frac{X-5}{95}\) + \(\frac{X-148}{8}\) = 0
Tìm x biết \(\frac{x-10}{30}\)+\(\frac{x-14}{43}\)+\(\frac{x-5}{95}\)+\(\frac{x-148}{6}\)=0
Tìm x biết :
a) \(\frac{x+11}{10}+\frac{x+21}{20}+\frac{x+31}{30}=\frac{x+41}{40}+\frac{x+101}{50}\)
b) \(\frac{x+2}{42}+\frac{x+4}{22}=\frac{x+5}{23}+\frac{x+3}{43}\)
c) \(\frac{x-10}{20}+\frac{x-20}{10}+\frac{x-30}{5}=\frac{x-14}{4}\)
Tìm x,biết
x-10/30 + x-14/43 + x-5/95 + x-148/8 = ?
