x+2/11+x+2/12+x+2/13=x+2/14+x+2/15
Tìm x
tìm x sao cho x+2/10^10+x+2/11^11+x+2/12^12=x+2/13^13+x+2/14^14
C) tìm x biết :
x + 2 / 11 + x + 2 / 12 + x + 2 / 13 = x + 2 / 14 + x + 5 / 15
Giúp mình nhé
Tìm x:
\(\dfrac{x-2}{11}+\dfrac{x-2}{12}+\dfrac{x-2}{13}=\dfrac{x-2}{14}+\dfrac{x-2}{15}\)
tìm x
\(\frac{x+2}{11}+\frac{x+2}{12}+\frac{x+2}{13}=\frac{x+2}{14}+\frac{x+2}{15}\)
Tìm x:
\(\frac{x-2}{11}+\frac{x-2}{12}+\frac{x-2}{13}=\frac{x-2}{14}+\frac{x-2}{15}\)
\(\frac{x+2}{11}+\frac{x+2}{12}+\frac{x+2}{13}=\frac{x+2}{14}+\frac{x+2}{15}\)
\(\frac{x+2}{11}+\frac{x+2}{12}+\frac{x+2}{13}=\frac{x+2}{14}+\frac{x+2}{15}\)
tìm x
\(A=\frac{x+2}{10}+\frac{x+2}{11}+\frac{x+2}{12}+\frac{x+2}{13}=\frac{x+2}{14}+\frac{x+2}{15}\)
