Răspuns :


[tex]\it x:\dfrac{5}{2} -\dfrac{1}{3} =7 \Rightarrow x:\dfrac{5}{2} =7 +\dfrac{1}{3}\Rightarrow x:\dfrac{5}{2} =\dfrac{22}{3} \Rightarrow x= \dfrac{22}{3}\cdot\dfrac{5}{2} \Rightarrow \\\;\\ \\\;\\ \Rightarrow x = \dfrac{55}{3} = 18\dfrac{1}{3}[/tex]

x:5/2-1/3=7
x:2,5-0,(3)=7
x: 2,5=7, (3)
x=7, (3) *2, 5
x=18.3333333333
