(x-13)/87+(x-27)/73+(x-67)/33+(x-73)/27=4
=>(x-13-87)/87+(x-27-73)/73+(x-67-33)/33+(x-73-27)/27=4-1-1-1-1
=>(x-100)/87+(x-100)/73+(x-100)/33+(x-100)/27=0
=>(x-100)*(1/87+1/73+1/33+1/27)=0
=>x-100=0
=>x=100
Tìm x biết
a) \(\frac{x+5}{95}+\frac{x+10}{90}+\frac{x+15}{85}+\frac{x+20}{80}=-4\)
b) \(\frac{x-13}{87}+\frac{x-27}{73}+\frac{x-67}{33}+\frac{x-73}{27}=4\)
Giúp mình với !!!!!!!!!!!
Đúng;cách giải rõ ràng sẽ tick
tìm x biết x-13/87+x-27/73+x-67/33+x-73/27=|1-4|.2019^0+1
tìm x thỏa mãn x-13/87+x-27/73+x-67/33+x-73/27=4
giúp mình mình tick cho 1 cái nha
không cần đúng nhưng có lí 1tí
thanks ^_^
Mấy bn ơi, giúp mk vs
Tìm x, biết:
\(x-0,27=\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{25\times\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)}\)
Tính P;
\(P=\frac{\left(13\frac{1}{4}-2\frac{5}{27}-10\frac{5}{6}\right)\times230\frac{1}{25}+46\frac{3}{4}}{\left(1\frac{3}{7}+\frac{10}{3}\right)\div\left(12\frac{1}{3}-14\frac{2}{7}\right)}\)
Ai đúng mk tích, cảm ơn các bn
\(\frac{x+17}{83}+\frac{x+27}{73}+\frac{x+37}{63}+3=0\)0
\(\frac{\left(27\frac{5}{19}-26\frac{4}{13}\right)\left(\frac{3}{4}+\frac{19}{59}-\frac{3}{18}\right)}{\left(\frac{3}{4}+x\right).\frac{27}{33}}=\frac{\frac{1}{13.36}+\frac{1}{14.17}}{\frac{1}{13.15}+\frac{1}{14.16}+\frac{1}{15.17}}\)

Tìm x:
\(\frac{\left(27\frac{5}{19}-26\frac{4}{13}\right)\left(\frac{3}{4}+\frac{15}{59}-\frac{3}{118}\right)}{\left(\frac{3}{4}+x\right)\frac{27}{33}}=\frac{\frac{1}{13.16}+\frac{1}{14.17}}{\frac{1}{13.15}+\frac{1}{14.16}+\frac{1}{15.17}}\)
Tìm x , biết :
\(x-0,27=\left(\frac{73}{77}+\frac{73}{165}+\frac{73}{285}\right):\left[25.\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)\right]\)
giải nhanh giúp mình nhé ! mình tick cho
Tìm x :
\(\frac{x+29}{31}+\frac{x+27}{33}=\frac{x+17}{43}+\frac{x+15}{45}\)
