Question

X + 1/2 x X = 4/5 mình cần gấp

​

​

​

​

Answer 1

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

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

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

\(x=\frac{8}{15}\)

Answer 2

X +1/2 x X = 4/5

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

X x ( 1+ 1/2 ) = 4/5

X x 3/2 = 4/5

X =4/5 : 3/2

X = 4/5 x 3/2

X = 12/10

X = 6/5

Answer 3

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

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

Xx ( 1 +1/2 ) = 4/5

XX 3/2 = 4/5

X = 4/5 : 3/2

X = 6/5

Answer 4

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

X x [1+ 1/2] = 4/5

X x 3/2  = 4/5

X          = 4/5 : 3/2

X          =   8/15
