21/4 . ( x – 71/3 ) = 1,5
x=8
9/4.(x-71/3)=15/10
15/10:9/4=x-22/3
2/3=x-22/3
x=22/3+2/3
x=8
$2\dfrac{1}{4} . ( x – 7\dfrac{1}{3} ) = 1,5$
$= \dfrac{9}{4} . ( x . \dfrac{22}{3} ) = \dfrac{3}{2}$
$( x . \dfrac{22}{3} ) = \dfrac{3}{2} : \dfrac{9}{4}$
$( x . \dfrac{22}{3} ) = \dfrac{3}{2}$
$x = \dfrac{3}{2} : \dfrac{22}{3}$
$x = \dfrac{9}{44}$
