Question

 

\(\frac{x}{25}+\frac{x}{30}=\frac{11}{3}\)

Answer 1

=>x/25=11/3-x/30

=>x/25=110/30-x/30

=>x/25=110-x/30

=>30x=25*(110-x)

=>30x=2750-25x

=>2750=25x+30x

=>2750=55x

=>x=2750:55

=>x=50

Answer 2

\(\frac{x}{25}+\frac{x}{30}=\frac{11}{3}\)

\(\frac{6x}{150}+\frac{5x}{150}=\frac{11}{3}\)

\(\frac{11x}{150}=\frac{11}{3}\)

Ta có:11x.3=150.11

          33x=1650

          x=1650:33

          x=50

Vậy x=50

Answer 3

\(\frac{6x+5x}{150}=\frac{11}{3}\Leftrightarrow\frac{11x}{3\times50}=\frac{11}{3}\Leftrightarrow\frac{x}{50}=1\Leftrightarrow x=50\)
