d.3x-1 totul pe 4 = 0,5 pe 3 va rog repede​

Răspuns:

[tex] \frac{3x - 1}{4} = \frac{ \frac{1}{2} }{3} [/tex]

[tex] \frac{3x - 1}{4} = \frac{1}{6} [/tex]

[tex]6(3x - 1) = 4[/tex]

[tex]18x - 6 = 4[/tex]

[tex]18x = 10[/tex]

[tex]x = \frac{10}{18} = \frac{5}{9} [/tex]

(3x-1)/4=0,5/3

(3x-1)/4=1/2/3

(3x-1)/4=1/2×1/3

(3x-1)/4=1/6

6(3x-1)=4

18x-6=4

18x=10

x=10/18

x=5/9
