Tìm x biết 59-x \41 + 57-x\ 43 + 55-x\45 + 53-x\47 + 51-x\49 = -5 . Giúp mình mình like cho . Ok. <3
\(\frac{59-x}{41}\)+ \(\frac{57-x}{43}\)+ \(\frac{55-x}{45}\)+ \(\frac{53-x}{47}\)+ \(\frac{51-x}{49}\)= -5
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
\(\frac{59-x}{41}+\frac{57-x}{43}+\frac{55-x}{45}+\frac{53-x}{47}+\frac{51-x}{49}=-5\) tìm x
\(\frac{x-5}{1990}+\frac{x-15}{1980}+\frac{x-25}{1970}=\frac{x-1990}{5}+\frac{x-1980}{15}+\frac{x-1970}{25}\) tìm x

Tìm x biết:
\(\dfrac{x+35}{65}\)+\(\dfrac{x+39}{61}\)=\(\dfrac{x+43}{57}\)+\(\dfrac{x+47}{53}\)
giúp mik vs ạ!
tìm x
x+43/57 + x+46/54 = x+49/51 + x+52/48
x+43/52+x+45/50=x+47/48+x+49/46.tìm x (/ là phân số, cộng cả phân số)
Tính các số đo x, y ở các hình 47, 48, 49, 50, 51.
