Question

[ 2.x - 0,6 ] + 0.25 =5\6

 

Answer 1

[ 2x - 0,6 ] + 0,25 = 5/6

[ 2x - 0,6 ] = 5/6 - 0,25

2x - 0,6 = 7/12

2x = 7/12 + 0,6

2x = 71/60

x = 71/60 : 2

x = 71/120

Answer 2

\(\left(2x-0,6\right)+0,25=\frac{5}{6}\)

\(\left(2x-0,6\right)=\frac{5}{6}-0,25\)

\(2x-0,6=\frac{7}{12}\)

\(2x=\frac{7}{12}+0,6\)

\(2x=\frac{71}{60}\)

\(x=\frac{71}{60}:2\)

\(x=\frac{71}{120}\)

Answer 3

( 2.x - 0,6 ) + 0,25 = 5/6

<=> ( 2.x - 0,6 ) + 1/4 = 5/6

<=> 2.x - 3/5 = 5/6 - 1/4

<=> 2.x - 3/5 = 7/12

<=> 2.x = 7/12 + 3/5

<=> 2.x = 71/60

<=> x = 71/60 : 2

<=> x = 71/120

Vậy x = 71/120
