Tim x biet: x+1/1974+x+2/1973+x+3/1972=-3
tim x biết (x+1) /1974 + (x+2) / 1973 + (x+3) / 1972=-3
Tìm x, biết\(\frac{x+1}{1974}+\frac{x+2}{1973}+\frac{x+3}{1972}=-3\)
Tìm x
59-x/41 + 57-x/43 + 55-x/45 + 51-x/49 = -5
x-5/1990 + x-15/1980 + x-25/1970 = x-1990/5 + x-1980/15 + x-1970/25
Tìm x:
\(\frac{x+1}{1974}+\frac{x+2}{1973}+\frac{x+3}{1972}=-3\)
tìm x
\(\frac{29-x}{21}\)+\(\frac{27-x}{23}\)+\(\frac{25-x}{25}\)+\(\frac{23-x}{27}\)-\(\frac{166-x}{29}\)=0
các bn lm giúp mk nha!!!!!
mk đang cần gấp!!!!!!!!
tính
\(\frac{-1}{3}+\frac{0,2-0,3+\frac{5}{11}}{-0,3+\frac{9}{16}-\frac{15}{12}}\)
tìm x :
\(\frac{29-x}{21}+\frac{27-x}{23}+\frac{25-x}{25}+\frac{23-x}{27}+\frac{21-x}{29}=0\)
giúp mình nhé thanks
\(\frac{x+1}{1974}+\frac{x+2}{1973}+\frac{x+3}{1972}=-3\)
\(\frac{x+5}{2005}+\frac{x+6}{2004}+\frac{x+7}{2003}=-3\)
TÌM X
Tìm x biết \(\frac{x+1}{1074}+\)\(\frac{x+2}{1974}\)\(+\frac{x+3}{1972}=3\)
