Question

x nhân 1/2 + 3/2 nhân x = 4/5 

Answer 1

\(x\)x   \(\frac{1}{2}+\frac{3}{2}\)x   \(x=\frac{4}{5}\)

\(x\)x     ( \(\frac{1}{2}+\frac{3}{2}\))  \(=\frac{4}{5}\)

\(x\)x     2                         \(=\frac{4}{5}\)

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

Answer 2

\(x.\frac{1}{2}+\frac{3}{2}.x=\frac{4}{5}\)   

   \(\frac{1}{2}x+\frac{3}{2}x=\frac{4}{5}\)

                  \(2x=\frac{4}{5}\)

                     \(x=\frac{4}{5}:2\)

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

Answer 3

X x 1/2 + 3/2 x X = 4/5

            X x ( 1/2 + 3/2 ) = 4/5 

            X x  2 = 4/5

                   X= 4/5 : 2

                   X = 2/5

Answer 4

x nhân 1/2 + 3/2 nhân x = 4/5 

\(x.\frac{1}{2}+\frac{3}{2}.x=\frac{4}{5}\)   

   \(\frac{1}{2}x+\frac{3}{2}x=\frac{4}{5}\)

                  \(2x=\frac{4}{5}\)

                     \(x=\frac{4}{5}:2\)

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

Answer 5

x.1/2+3/2.x=4/5

x.(1/2+3/2)=4/5

x.4/2=4/5

x.2=4/5

x    =4/5:2

x     =4/10=2/5

Answer 6

x.1/2+3/2.x=4/5

2x=4/5

x=4/5.1/2

x=2/5
