3-x / 5-x = 6/11 nhanh nhá

1. $\frac{3-x}{5-x}$ = $\frac{6}{11}$

   <=> 11(3-x) = 6(5-x)

   <=> 33 – 11x = 30 -6x

   <=> 6x – 11x = 30-33

   <=> -5x = -3

   <=> x = -3 : (-5)

   <=> x = $\frac{3}{5}$

   Vậy x = $\frac{3}{5}$

   Trả lời
2. (3-x)/(5-x)=6/11

   =>11 . (3-x)=6 . (5-x)

   =>33-11x=30-6x

   =>-11x+6x=-33+30

   =>-5x=-3

   =>x=3/5

   vậy x=3/5
