Question

\(\frac{2}{3}x-\frac{1}{2}x=\frac{5}{2}\)

Answer 1

Ta có \(\frac{2}{3}\)x-\(\frac{1}{2}\)x=\(\frac{5}{2}\)

         x*(\(\frac{2}{3}\)-\(\frac{1}{2}\))=\(\frac{5}{2}\)

         x*\(\frac{1}{6}\)=\(\frac{5}{2}\)

        x=\(\frac{5}{2}\):\(\frac{1}{6}\)

        x=15

Answer 2

2/3 x - 1/2 x = 5/2

(2/3 - 1/2) x = 5/2

     1/6 x = 5/2

           x = 5/2 : 1/6

           x = 15

Vậy x = 15

 

Answer 3

\(\frac{2}{3}x-\frac{1}{2}x=\frac{5}{2}\)

\(x.\left(\frac{2}{3}-\frac{1}{2}\right)=\frac{5}{2}\)

\(x.\left(\frac{1}{6}\right)=\frac{5}{2}\)

\(x=\frac{5}{2}:\frac{1}{6}\)

\(x=15\)

Vậy x=15

Answer 4

x.(\(\frac{2}{3}\)-\(\frac{1}{2}\))= \(\frac{5}{2}\)

x.\(\frac{1}{6}\)=\(\frac{5}{2}\)

x=\(\frac{5.6}{2}\)

x=15

Answer 5

\(\frac{2}{3}x-\frac{1}{2}x=\frac{5}{2}\)

\(\left(\frac{2}{3}-\frac{1}{2}\right)-x=\frac{5}{2}\)

\(\frac{1}{6}-x=\frac{5}{2}\)

\(x=\frac{1}{6}-\frac{5}{2}\)

\(x=\frac{-7}{3}\)

Answer 6

\(\frac{2}{3}x-\frac{1}{2}x=\frac{5}{2}\)

\(\left(\frac{2}{3}-\frac{1}{2}\right)x=\frac{5}{2}\)

\(\left(\frac{4}{6}-\frac{3}{6}\right)x=\frac{5}{2}\)

\(\frac{1}{6}x=\frac{5}{2}\)

\(x=\frac{5}{2}:\frac{1}{6}\)

x=15

Answer 7

2/3.x-1/2.x=5/2

 x.(2/3-1/2)=5/2

 x.1/6=5/2

 x=5/2:1/6

 x=5/2.6/1

x=15

Answer 8

(2/3-1/2).x=5/2

(4/6-3/6).x=5/2

1/6.x=5/2

      x=5/2:1/6

      x=5/2.6

       x=30/2

       x=15
