afla nr x din egalitatile x+(4/9-1/9)=1​

Răspuns :

=> x+ 3/9 =1
x+1/3 =1. |*3
3x +1 = 3
3x = 2 => x= 2/3

Răspuns:

[tex]x+ (\frac{4}{9} -\frac{1}{9} ) = 1[/tex]

[tex]x+\frac{4-1}{9} =1[/tex]

[tex]x+\frac{3}{9} = 1[/tex]

[tex]x+\frac{1}{3} = 1[/tex]

[tex]x=1-\frac{1}{3}[/tex]

[tex]x=\frac{3-1}{3}[/tex]

[tex]x=\frac{2}{3}[/tex]
