Question

Tìm x :
2/5 nhân x+1/3 nhân x=3/5

Answer 1

11/15x = 3/5

=> x =  3/5 : 11/5 = 3/11

Answer 2

\(=>x=\dfrac{3}{5}:\left(\dfrac{2}{5}+\dfrac{1}{3}\right)=\dfrac{3}{5}:\dfrac{11}{15}=\dfrac{9}{11}\)

Answer 3

9/11

Answer 4

2/5 x X+1/3 x X=3/5

( 2/5 + 1/3 ) x X = 3/5 

         11/15  x X = 3/5

                       X = 3/5 : 11/15

                      X =       1/11

Answer 5

\(x=\dfrac{2}{3}\)

Answer 6

\(\dfrac{2}{5}\times x+\dfrac{1}{3}\times x=\dfrac{3}{5}\)

        \(x\times\left(\dfrac{2}{5}+\dfrac{1}{3}\right)=\dfrac{3}{5}\)

        \(x\times\dfrac{11}{15}=\dfrac{3}{5}\) 

        \(x=\dfrac{3}{5}:\dfrac{11}{15}\)

        \(x=\dfrac{3}{5}\times\dfrac{15}{11}\)

        \(x=\dfrac{9}{11}\)

Answer 7

2/5 x X + 1/3 x X = 3/5

X x ( 2/5 + 1/3) = 3/5

X x 11/15 = 3/5

X = 3/5 : 11/15

X = 9/11
