\(\dfrac{2}{3}x+\dfrac{3}{4}=\dfrac{5}{6}\)

Answer 1

\(\dfrac{2}{3}x+\dfrac{3}{4}=\dfrac{5}{6}\)

\(\dfrac{2}{3}.x=\dfrac{5}{6}-\dfrac{3}{4}\)

\(\dfrac{2}{3}.x=\dfrac{10}{12}-\dfrac{9}{12}\)

\(\dfrac{2}{3}.x=\dfrac{1}{12}\)

\(x=\dfrac{1}{12}:\dfrac{2}{3}\)

\(x=\dfrac{1}{12}.\dfrac{3}{2}\)

\(x=\dfrac{1}{8}\)

 

Answer 2

\(\dfrac{2}{3}.x+\dfrac{3}{4}=\dfrac{5}{6}\)

\(\dfrac{2}{3}.x=\dfrac{5}{6}-\dfrac{3}{4}\)

\(\dfrac{2}{3}.x=\dfrac{1}{12}\)

\(x=\dfrac{1}{12}:\dfrac{2}{3}\)

\(x=\dfrac{1}{12}.\dfrac{3}{2}\)

\(x=\dfrac{1}{8}\)

Answer 3

x=\(\dfrac{1}{8}\)

Answer 4

2/3x=5/6-3/4=1/12

x=1/12:2/3=1/8

Answer 5

`2/3 x+3/4=5/6`

`2/3 x =5/6-3/4`

`2/3 x=1/12`

`x=1/12:2/3`

`x=1/12xx3/2`

`x=1/8`

Answer 6

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

2/3.x=20/24-18/24

2/3.x=1/12

x=1/12:2/3

x=1/12.3/2

x=1/8

Answer 7

<=>\(\dfrac{2}{3}x=\dfrac{5}{6}-\dfrac{3}{4}\)

<=>\(\dfrac{2}{3}x=\dfrac{1}{12}\)

<=>\(x=\dfrac{1}{8}\)
