Tìm x:
\(\frac{\left(27\frac{5}{19}-26\frac{4}{13}\right)\left(\frac{3}{4}+\frac{15}{59}-\frac{3}{118}\right)}{\left(\frac{3}{4}+x\right)\frac{27}{33}}=\frac{\frac{1}{13.16}+\frac{1}{14.17}}{\frac{1}{13.15}+\frac{1}{14.16}+\frac{1}{15.17}}\)
x2 =\(\frac{4}{5}.\frac{15}{27}\)
tìm x
\(\frac{x}{15}\)+\(\frac{27-x}{5}\)=\(\frac{x}{4}\)+\(\frac{27-x}{12}\)
giúp mình vs mn ....
Tìm x biết
a) \(\frac{x+5}{95}+\frac{x+10}{90}+\frac{x+15}{85}+\frac{x+20}{80}=-4\)
b) \(\frac{x-13}{87}+\frac{x-27}{73}+\frac{x-67}{33}+\frac{x-73}{27}=4\)
