Question

a) 2/9 - 7/8 x X = 1/3

b) (14,17 - x) x 2/9 = 1/3

Answer 1

\(a,\dfrac{7}{8}x=\dfrac{2}{9}-\dfrac{1}{3}\\ \dfrac{7}{8}x=\dfrac{2-3}{9}\\ \dfrac{7}{8}x=-\dfrac{1}{9}\\ x=-\dfrac{1}{9}:\dfrac{7}{8}\\ x=-\dfrac{8}{63}\\ b,14,17-x=\dfrac{1}{3}:\dfrac{2}{9}\\ 14,17-x=\dfrac{3}{2}\\ x=14,17-\dfrac{3}{2}\\ x=\dfrac{1267}{100}\)

Answer 2

`a)`

` 2/9 - 7/8 xx x = 1/3`

`=>  7/8 xx x =2/9 - 1/3`

`=>  7/8 xx x =2/9 - 3/9`

`=>  7/8 xx x =-1/9`

`=>x=-1/9 : 7/8`

`=>x= -1/9 xx 8/7`

`=>x= -8/63`

`b)`

`(14,17 - x) xx 2/9 = 1/3`

`=> 14,17 - x=1/3 : 2/9`

`=> 14,17 - x=1/3  xx 9/2`

`=>  14,17 - x=3/2`

`=>x=   14,17 - 3/2`

`=>x=12,67`

Answer 3

\(=\dfrac{7}{8}.x=\dfrac{2}{9}-\dfrac{1}{3}\Rightarrow\dfrac{7}{8}.x=-\dfrac{1}{9}\Rightarrow x=-\dfrac{1}{9}:\dfrac{7}{8}\Rightarrow x=-\dfrac{8}{36}\)

\(------------------------------\)

\(=14,17-x=\dfrac{1}{3}:\dfrac{2}{9}\Rightarrow14,17-x=\dfrac{3}{2}\Rightarrow x=14,17-\dfrac{3}{2}\Rightarrow x=\dfrac{1267}{100}\)
